Can anybody try to make a TGA larger than 3000x2000 pixels? with VRAY and 32 bit alpha channel??
Because i cant?? :confused: |

It also depends on your video card I think. I have another program that can 3D paint 8192x8192, but my video card and monitor (6800XS Nvidia) won't handle it.
That 3D Painter Software specifically states in the software that the video card is the primary factor when it comes to resolution of painted objects.
I don't know about tS7, I suppose they have a high end resolution maximum. |

Thanks, for the reply..
I think i must reinstall ts.. Because in Lightworks works fine.. only with Vray.. thats the problem :rolleyes:
Indeed i must reinstall all the os... but i dont have time to do that.. :( |

VRay render size limit is set by available RAM size. There is no limit set by tS so results will vary from person to person and machine to machine - it can even vary on the same machine depending on the scene itself and what else the machine is running. I'd have to guess that saving with Alpha channel will also decrease the maximum size too. |

Upgrade to wife 2.0 and uninstall the kids - it won't help the VRay renders but you'll be a lot happier.....:) |

I found the problem.. plz confirm...
I cant Render 3000x2000px because im using X4 antialiasing..
X3 with the same result..
x2, none and adaptive works fine..
Its like Vray render try to render 3000x4 x 2000x4 and the render image size be exeded...
Is like it want to render a 12000x8000 image...
If that is correct, that is a bug.. :(
Works fine on ligthworks.. |

I just dialled it up to 4xAA and set it to work. It's now crunching away, both CPUs on full throttle.
I'll give it a while before I cancel, but it seems to be working. |

That's exactly how it works. Not a bug, just the way it is. |

Ok. thanks bobbins, now im more happy to find the problem..
Now... are few things..
1) You know the vray image size limit??? Ligthworks far as know is 8000x8000 (correct me if im wrong). I need that info to know how bigger i can make a render on vray.. On my work sometimes i need make renders for posters and i need the most high res and quality as posible..
2) That works on Lightworks.. you know if that is posible to "fix" on future releases???
3) If its not posible support 8000x8000 x4 antialiasing "I Think" thats must be documented on the manual .. Because as i found, you cant render.. and you can wait a few hours and nothing happend. And its dificult to the final user understand the problem is antialiasing x4 or x3 and thats the same like multiplicate the res x the number of the antialiasing.. Thats a problem, well now if search on the forum maybe find this...
4) 3000x2000 pixel is not a very high res render, even if you cant use antialiasing.. Thats why i think its a big limitation..
5) Thanks ;) and if you can, try to report this case maybe is a simple thing. |

I'll re-iterate my reply. VRay for tS has no upper size limit for renders. The maximum size you can render is capped by the amount of available RAM.
If you run more applications then you have less available RAM and maximum render size decreases.
If you have a very complex scene with lots of textures, it has to be loaded in Model view and in Player view so you have less available RAM and maximum render size decreases.
If you don't have a lot of RAM, then you have less RAM and maximum render size decreases :)
It really is that simple so it's not possible to give any guideline as to the maximum render size you might be able to achieve on any given PC for any given scene. There are just too many variables. If it had to be documented then the documentation would have to say "there is a maximum render size for VRay. The maximum render size depends on the amount of available RAM". |

Maybe a few people need to set up some test scenes and see what the range is.
What is enough ram?
Should be an idea of how much ram is needed under Windows XP...I would think.
Since their is a limit on effective ram under XP, this would be reasonably easy to narrow down to establish some ranges. |

Let's put it this way - if I set up a single sided plane with one light and applied a huge texture to that plane, say an 8Gb TIF file, how big would you be able to render it? 1x1 pixel would fail because you would be out of RAM due that TIF file texture.
Does that answer your question? |

Lets do something.. someone can render in vray a sigle plane in 3000x2000 x4 px??? i cant with 1g ram 500 system memory free..
Maybe those guys with 2g can aswer my question ;) |

Ok Prodigy - I've called your bluff.
I set up a single sided plane at the origin. The plane size was 0.001x0.001x0. I rendered to TGA file under Vray for tS 1.0 with 4xAA at 4000 x 2000 ( so I beat your 3000x2000 challenge).
Obviously, default texture was used on the plane, no caustics, no GI, no triangulation, nothing else that would increase the memory useage.
It rendered fine, I can open the TGA file in PhotoShop CS2 correctly.
P4 3.2 Ghz HT with 2Gb RAM.
As I've said all along, the maximum VRay size is limited by available RAM. If you have a complex scene, if you have other programs running on your PC, if you have large textures or procedural textures used or if you have less than an optimal amount of RAM installed on your machine or a poor swap file size, your result will of course vary.
End of. Over to you. |

Since Windows machines run a limited amount of memory that would be one known factor.
Another factor would be the dimensions of the object and the procedural texture.
If these three things are known, why can't a chart be made out, let's say...some guy who likes scripting...to calculate how much time it would take to render said object.
If it goes into a red warning area it might have trouble running and green area should run.
Someone could make a script calculator determining that I would think. |

Bobbins.. i apreciate all your support realy..
Im not happy looking we can render a 4000x2000px 4x on with 2g ram.. a single poligon without gi texture and bla bla bla.. Its not something to be proud..
In other words, thanks because i stop my idea to buy more memory ;)
And
I can render a complex scene with 1g at 6000x4000 x2 and thats fine for me.. :jumpy:
Thanks... again!! :) |

Has to be said that 1 Gb is not that much these days - that's what I have, and my system eats some 300 to 400Mb of that just doing nothing. Add in tS, and maybe Photoshop, and email, and a couple of internet explorers, and a windows explorer or three, and I often find I am using 600 or 700Mb - not much spare for things like rendering.
2 Gb should make a big difference to the size of things you can render, and is probably the best move. Cutting down on other apps running at the same time should help too.
HTH!

Yeap Norm, i know.... thanks to you and to Bobbins.. ;)
As i told, i render the watch in 6000x4000 pixels x2 without problems.. thats fine for me... yup maybe in the future i buy some extra giga... but no now... here anything its expensive.. 140 U$S 1 giga for dual channel... how much cost in USA?? |

Depends on what brand you buy - have seen it at around $110 per Gb or so, but not much lower than $99 ever.
I like NewEgg.com myself (personal recommendation, absolutely not an official Caligari statement or endorsement of any kind). Would be a good place to keep an eye on prices. I'm actually getting all the bits to build myself a new machine this week (finally moving away from AGP to PCI-E!), and I did get 2Gb of DDR2 800 for $170 (special offer reduced from $210 or so), which works out at a very good price per Gb. It's not however one of the super duper brands of memory like Corsair (it's G-Skill, got good enough reviews for me to feel comfortable buying it).
HTH!

Im still working on AGP :( but works very nice for my work and for games.. :)
I think im gonna change my pc on a few years.. when microsoft lauch DX11 :D
You see Core 2 Quad??? Wow.. here cost 1100 U$S very expensive at this moment.. but who knows in a few years... maybe we have core 2 ten
Buy the last technoloty is very expensive, i allways recomends wait a few years ..
TOMG, Happy Buy!! |

the maximum VRay size is limited by available RAM
Just musing here and no problem with that at all...
Does RAM in this context mean (in effect) only system memory or does it mean (system memory + pagefile)?
If as usual the pagefile takes the overflow maybe you have too small a pagefile Prodigy?
It would be very slow lento :) but plenty room in the pagefile for very big files
2GB Corsair good stuff here and a large pagefile safety belt

I believe it would be system memory only. Though I havent put it to the test or received tech info that says this.
From what I've seen though V-R only really uses your physical memory and if it runs out then it can't render. Could be wrong there, but if it gets into using your page file it would seriously slow render time down anyway.
Finally got a 2Gb system and it makes a nice difference to just about everything :)
HTH!

I believe you are correct on the dimensional limit for Ligthworks with just tS, however, if you had tSNet (http://www.caligari.com/Products/trueSpace/ts5/plugins/caligari/tSNet/default.asp?Cate=Caligari) you could go upto 64000x64000.
2 Gb should make a big difference to the size of things you can render, and is probably the best move. Cutting down on other apps running at the same time should help too.
Very true, I'd recommend 2GB to anyone using tS7.x.

Yeah, I certainly noticed the difference when I went from 1GB to 2GB |
