Splats are triangular no matter the falloff value

[DarioMazzanti]

Thanks for the plugin! Everything seems to work fine for me, but I cannot seem to make the splats round: they are always triangular.

I tried changing the falloff value, but I only seem to be able to get binary results:

• falloff values grater than 0 --> full triangle
• falloff values of 0 (or less) --> fully transparent splat

I also tried masked as well as transparent blend modes, getting the same result. I looked into the material, and the part related to opacity does exactly what you describe in your thesis ( well, of course! :) ) Is there some setting I need to look into, or something I am forgetting? I am working on master_4.19 branch.

Thanks!

hey dario,

I would recommend to use the master branch (for UE4.21 and not UE4.19) because the older versions still might be a bit buggy ;)

let me know if that helps.

Hey! Unfortunately my team needs to stick with UE4.19, at least for some time, since we have many plugins which would require us some effort updating.

Anyway, I slightly modified the shader and now I can see the splats as circles :) I am using the original positioning as input for computing the round shape, instead of the UVs. I am not sure that is 100% correct - it seems to work properly though:

Thanks again!
