Hi all,

I was experimenting with sprites and trying to learn how to render with them.

I did a manual setup via the docs, and the sprite I'm using is just a simple rendered fluid cloud saved as a cloud.tif with a alpha.

After I applied the cloud.tif to the shader which is applied to the particles, the cloud is black instead of white.

When I render the sprites in the hardware render buffer, they are black also.

Why is the color of the cloud reversed?:shrug:

Help!

have u added per object colour attribute to the particles
if thats the case check if the RGB colour values are 0,0,0
change them to 1,1,1
hope thats the correct answer to ur query
best luk

waltz,

Thanks for the input.

I did have a rgbPP attribute that I used to test the lifespan (lighter the color the longer they live), but I forget to delete the attribute.

I just deleted it & added a rgb Per object attribute & set the RGB to 1.00, which made my cloud visible.
