Particle Textured -Render in Image

aboiledtiger's picture

Hi: I have a problem trying to render in an image a textured particle scene. Everything works ok but when I try to render it in a RenderInImage patch the particles stop showing. (nothing at all) It only happens with the ParticleRender:Textured. Not with Standard that works fine. I already tryed changing image size and depth test settings with no succes. I'm using OSX10.5 on a mac book pro.

Thanks. DX™

I can render particles in a render in image but its slower and intermittent.

The actual texturing doesn't get conveyed, though the shapes do get reproduced, not even if I only RII the particle render patch.

I don't get the console, log messages you post here.

I suspect a mismatch Particle Tools version wise, not sure though.

I used the red wedge example and replace d the VBO with the textured particles patch.

RII particles - yes - but very slow with VBO and / or Textured.

RII textured by image input - no .

On 10.6.x in QC 32 bit.

Non RII Particles do texture up.

Re: Particle Textured -Render in Image

It's not a particle tools mismatch; it's a known limitation... this happened to some extent in Leopard as well (but I think the problems look slightly different in SL(?)).

Here are some workarounds:

-Use the structure:render patch from Particle Tools, and then use a GL Point Structure Renderer; texture the Points.

-Use the structure:render patch from Particle Tools, then connect output to the GL Structure Render Environment. Inside of that, place some small Sprites that are textured with the desired image.
