Vray 1.5 shaders slow down truespace // Roundtable 1  |   Order by default Post by mykyl1966 // Jun 6, 2007, 12:14pm mykyl1966 Total Posts: 221 Vray shaders slow down Truespace. If I try and use any of the vray shaders apart from plain color and image map, I find that Truespace slows down a huge amount. Everything else works well its just this one thing. Doesn't make sense really but its not a slight slow down. I could choose the vray brick shader lets say and wait about 15 seconds before I can do anything else. This includes changing the settings of the shader. ... I have just checked and it takes between 9 seconds and 25 seconds depending on which shader is being chosen. 9-25 Seconds to load the shader...9-25 seconds to change a setting... 9-25 seconds to change it back a bit as it changed to far... 9-25 seconds.... Well you get the picture I hope. lol. Plain color and image are the only ones that load with no delays. Makes it all a bit useless trying to do anything properly in Vray. Any ideas or is this a bug.

Mostly the checkered ones, but als the wood and bricks. I get no slow down at all. Have you made sure you have updated drivers etc..? Post by mykyl1966 // Jun 6, 2007, 2:59pm mykyl1966 Total Posts: 221 If I install the latest gfx drivers then all of Truespace slows down or crashes bringing my entire pc down with it. I fought with that for a couple of days before going back to earlier drivers and had no problems ever since. Except for now.

Cheers Mike R Post by transient // Jun 6, 2007, 3:02pm transient Total Posts: 977 Vray shaders are slow to update for me too, but not unbearably. Apparently the material section is a live vray render which could be contributing to it's sluggish performance. Post by mykyl1966 // Jun 6, 2007, 3:17pm mykyl1966 Total Posts: 221 Oh. Now thats a pain then. As its of no use to me and past my 30 day money back for Vray if I have to wait for each slight change. Cheers Mike R Post by transient // Jun 6, 2007, 4:28pm transient Total Posts: 977 Personally I think you're better off hanging on to vray as it's rendering quality is excellent imo. You can turn off the live update as well which should speed things up. I'm using a sempron machine with a 6600gt and I don't seem to be suffering any widow-making slowness. I guess if you're really that disillusioned with it maybe you can talk directly with Caligari for a refund as you're only just over the 30 day money back by my calculations. Post by mykyl1966 // Jun 6, 2007, 4:54pm mykyl1966 Total Posts: 221 I will have to have a look at how to switch off the live update as you called it. I still find it strange though as I can render full scenes with GI and texture maps quicker than 20 seconds at 640x480. lol. Maybe not quite that quick but its pretty fast. Cheers Mike R Post by mykyl1966 // Jun 7, 2007, 4:35am mykyl1966 Total Posts: 221 Why do I need to use the vray shaders (brick etc) when the ones in model view work and render perfectly well in vray anyway??? Is there something I am missing? At least this way I don't get pause start all the time and can just get on and work. Thank goodness. :D Cheers Mike R Post by mykyl1966 // Jun 7, 2007, 4:55am mykyl1966 Total Posts: 221 Spoke too soon. If your model is created in Workspace certain things don't translate well between model space and workspace so holes can get closed etc so you end up with a wrecked model. Back to the drawing board. Mike R Post by mykyl1966 // Jun 7, 2007, 11:39am mykyl1966 Total Posts: 221 Just been looking round the forums and the series of images on this thread is what I have been seeing. http://forums1.caligari.com/truespace/showthread.php?p=37374#post37374 Really a pain as if this problem was fixed then the slow response of vray shaders would be irrelevant.
