Choose only 1 random static Tex3D image?

Beginners

My simple particle system currently cycles through 30 images in the Tex3D.

How to make the particle system only choose 1 random image and no cycling? (Ie all the particles will be different, with all 30 images represented across all the birthed particles)

You’ll need to use Instancing to render your particles to sprites and then use Texture Replace’s W parameter as your offset into your 30 images.

You will then need a w offset for every instance (particle) which can be done in SOPs directly but it is probably easier and better performance in CHOPs.

Recommend uploading an example file of where you are at so far as its much easier to help by adding your existing network.

Thanks Ben.

I did some more digging and also found a related answer here and their Toe example with using the W in this thread:

Really happy everyone in this community shares :slight_smile:
