Rendering API, custom render pass

[vadim.lisev]

Hello. I'm new in Unigine.

Is there any API for custom rendering? 

I try find some functions like:

Graphics.SetRenderTarget(RenderTarget color, RenderTarget depth) - setup current rendering target texture

Graphics.DrawMesh(Mesh mesh, Matrix4x4 matrix, Material material) - render mesh with specified localToWorld matrix and material

These functions are from Unity :)
My goal is system that can render meshes with specified materials to my custom RenderTarget. After that I want do "Blit" this RenderTarget after final image of scene will be rendered (post-processing). It will something like X-ray rendering of meshes, to highlight mesh if it placed behind surface.

 

I work with C# project.

Hello Vadim,

There is a class RenderTarget in the engine for render target textures configuration
https://developer.unigine.com/en/docs/2.9/api/library/rendering/class.rendertarget?rlang=cs

And mesh rendering can be done with Object.Render method
https://developer.unigine.com/en/docs/2.9/api/library/objects/class.object#render_int_int_void

Is there any more description regarding RenderTarget .

The doc is too simple and without samples.

Is it possible to provide some more detailed guidance here for how to do a typical Blit operation?  I want to copy the contents of 1 texture to another, preferably using a specific material to render the output texture.  I've looked at the RenderTarget docs, but without an example of useage I'm having trouble deciphering them.
