Animated sprites for OpenGLRop

Recommended Posts

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!

OsX10, H15.5.523

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. :lol:

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.
