    Hello all! I have blood effect, that throwing forward. It spawn another particle when its collide with plane. As you can see on giff, new particle is always the same with horizontal and vertical plane. Is there any way to change behaviour or spawn another particle when colliding vertical plane ? upload_2022-4-18_15-57-51.gif

    Try using Decal outputs in your Blood spots GPU event system:


    It should give you something like this:


    If your decal is looking strange, you can also try using different Orient blocks and/or adding an Add Rotation in the output and rotating the particles until the decal is aligned to the surface you want.

    I also did it with "compare" block. If dying particle too high, then spawn 1 particle that has another angle. Else - spawn 0 particle with this angle. It works, but dont think it`s the good way to use compare statement because of GPU. upload_2022-4-21_11-41-32.png upload_2022-4-21_11-42-7.png
