Animated sprites for OpenGLRop

[Guest tar]

Does anyone know if animated sprites are supported in the viewport? i.e. for OpenGLRop Rendering.

Simple tests so far only have Mantra picking up the animated frames.

Thanks!

I could see the frames in my OpenGL render.

I applied a Mantra surface to a grid with UVs set to orthographic.

I assigned an animated footage sequence to the material diffuse slot.

I rendered using OpenGL to the ip viewer and I could see the image in the render result. The image changed over time as I tested various renders along the timeline.

thanks - did it work for sprites? i.e. a sprite applied to a point

You can, of course, instance a grid to a point.

It may have to be that way! Anything is better than NukeX's so-called particle system.

There is the "texture atlas" option in the sprite node, but looks like it does not allow per-particle phase for the animation. If all the textures animate globally at the same time, that is of course less than desirable.

Doing the uv manipulation (scrolling the x uv in the atlas by one subtexture increments) by hand in an attribute wrangle seems to do the trick.

Nifty!

There is bug id for the original issue too now. (ID=76422)
