Hello ts Gurus,
I'm new to truespace, but decided to go with 7.5 based on the price and features. I work with a team of video, graphic and 3D artists in a corporate environment. They all use Maya. I'm going to try to outshine them by doing a quick project in truespace. Here's what I need to do:
- Work with existing video of a guy walking around a scene with a clipboard pretending to check out a race car.
- Use a high-quality model of a car (we have purchased it in both Maya and 3DS Max format), and place it in the scene. By the way, we shot the video with a chrome ball showing sun position.
That's it. Two camera angles. I'd like to render two stills with alpha channel (.png?) that have the lighting and shadows appropriate, and composite into the video making the car look like it is in the scene.
In 3DS Max, I had to render the shadows onto a plane mapped with matte/shadow material to get only the shadows in the image. Do I have to do that in ts? Will the shadows show up inb the renders as long as I line up the ground plane? Is there a way to cast shadows upon another surface and only render the shadows in ts?
Any other suggestions as to the best way to proceed? I have 7.5 + v-ray.
Thanks, Pablo |

You'll probably have to wait for the patch for alpha on the png/tga export, because if I remember right that's not currently supported in the 7.5 release.
How are your car textures done? If they are Max materials, they might not import, so you may need to redo the materials for the car. Hopefully you have the texture maps as separate files?
I'm not sure about the shadows. I'm sure there's a way to do it, but I've never tried before.
You may want to start a WIP thread and post images of your progress so you can get advice more directed towards specific problems you are having with the project.
Wish I could help, but compositing isn't my thing. I'm sure there are others with more experience with that... problem is that they probably haven't been using 7.5 that much longer than you have. ;) Hopefully one of the other beta testers will be able to give you more specific help.

there was once a shadow catcher shader for ts 6, I'm not sure if it was a plugin or a native shader???you may want to check that out. |

shadowcatcher is a shader.
You set your existing real photo as backgroundimage and set a 2D Plane as ground, tweak it like the ground in your backgroundimage and paint it with the shadowcatcher shader.
Than you bring your Car model in scene and place it on your 2D ground. Now you need a light that generate shadows.
Than you can delete the Backgroundimage and render the tweaked 2D Plane with the imported car.
You get shadows of the car on the 2D Plane and bring it to photoshop or what ever you will try with it.
Take *.tga as file output. |

Hi Pablo did you look at the HDRI/HDRL setup?
