I really need help with every aspect of transparency I’m almost clueless with how to have a transparent image, is it to do with the picture which you import into unity such as adding transparency in Photoshop ect? Or can you add transparency in unity to any image you want?
I’m making a particle effect and I need a transparent image for a blood splat please can anyone help?
You are on the right track. Using something like Photoshop create the shape you want. Make sure there is no background. ie in Photoshop create it a new layer and deselect the background layer. Then save it in a graphic format that supports transparency. PNG is ideal. You can then drag the picture in as an asset and start using it for textures.
Lastly you should try size it in a friendly texture size for the shaders, like a square 256x256, 512x512, 1024x1024 etc. Smaller, the better.
if you want per-pixel transparency, which you will for blood splatters, you’ll need to do it in photoshop; unity can only set a single alpha for the entire image, which will not produce the results you’re looking for.
Once you’ve got one, I’m assuming you want these to hit and persist on walls/floors, and textures applied that way are called decals. A search for decals will find you quite a bit of information on the subject!
