2.5d rendering and compositing

Unread postby kentonia » Sun Mar 05, 2017 9:46 pm

Hi

Can someone please provide detail on how the picture in picture feature works for using 2.5d renderings of several 3d scenes and compositing them to make one large scene in a a clarisse project. Can't seem to find detailed tutorials on the subject.

Cheers.

Hi,

Please look at the 3dmatte project in the contents which does what you are looking for. You should have a look at our tutorials page.

Here's another tutorial featuring the Render to texture (picture in picture)

Thanks for the heads up on this. However I did see a webinar I think in which a large environment was created out of several 2.5d renderings. Each rendering/Image was obtained from a texture cap (not sure what it was called). Would I be correct to say that the texture caps are simply matte plane objects textured with the output image of the different 3d scenes in the one project? If so what would be the appropriate texturing/material assignment structure

Cheers

Hi Kentonia,

Yes, to use the render to texture feature, you just need a classic texture graph with a "decal" material (to be able to use the alpha) on a simple grid. As color input, you need to use a map node (not a map file node ) that allows you to choose one of the images of your project.

the best way to organize the project is to create a context for each image.

For the light, create a group and set it in the layer visibility to share the same in all images.

For the images, you want to use in your cards, create a new raytracer and keep the camera samples value to 1 to be sure to not have antialiasing issues on the alpha.
