Blend modes on textures (sprites and particles)

30 November 2016 07:39 #14252
I will be creating fireballs with particle effects to demo some game assets, and I plan to use a combination of animated image sprites (camera-facing billboard images) and particles.

Here is a reference, as an example of the sort of thing I want to make.

What I can't figure out is how to change the "blend mode" to additive in order to remove the black background and make the fire appear as if it is glowing.

Here is an example of what I hope to achieve (although this was made using an image editor):


Thanks in advance for any help!

You will need just to set black background as aplha chanel using GIMP or another image editing program. Look how it's made in Petigor's Tale game for torchlight's fire in petigors_tale/vfx/fire_n_smoke.blend file..
Blend4web and that kind of thing.
