I thought that you painted the texture first then fit the UV around it later

I used to care about keeping quads on flat non-deforming surfaces that wouldn’t be subdivided. Making a cornhole board would’ve taken me half an hour as I tried to keep quads

It's okay anon.
I did the same thing too, well kinda.
I did one leaf and then made a tree out of it, but it doesn't make it any less retarded.

Each tree is 500k verts. Pretty much unusable in a large scene with a bunch of trees. I could always instance, but it's still a lot of geometry for a tree.

Palm trees are retarded.

Actually, digging through some older files, looks like I did have the intelligence to make alpha planes out of them.
Though it's still makes scenes pretty heavy, not with geo, but a bunch of alpha planes can really bog shit down.

It’s embarrassing but not retarded

I practiced making organic shapes by modeling sextoys. Anal beads, fleshlight lights, dildos, etc. sextoys are a good category of objects to practice with

Really though?
I feel like it's as good practice as learning those lathe operations to make chess pieces.
You can make millions of sex toys with just a curve profile.
It doesn't seem like there's much to learn there.

Exporting 8k textures from SP and still getting mad because I couldn't get the texture on the model to look sharp enough. It was an entire building I tried to texture uniquely with a single UV set.

I'd do it the same way probably.
Reading the OP made me remember that I did the same thing, but I guess I misremembered about doing the alpha planes.


So yeah, using alpha planes definitely was the way to go in terms of performance, but you're gonna run into issues using a bunch of layered alphas on any GPU just because of how it fucks with draw calls.
Apparently as well I was being retarded and using an 8k map, so that probably had some influence on it as well.

In any case, figured I'd share the texture anyway. It's just a 2k normal map with an alpha channel, since I wanted to be able to color the leaves procedurally.
Plug the normal map up, and use the alpha for alpha and it should work fine. Though I probably fucked up the normal bake.

Leaves colors run in a limited gamut of green and yellows, would it be cheaper in performance to use a gif with an indexed transparent color?

You're right, but when I was first going about using it, I wasn't just focused on greens/yellows, more weirder colors like Red or Infrared. I know it's a simple thing to just put the color info into the texture, but it didn't really seem all that necessary to me.

But yeah, the alpha issue doesn't really have anything to do with how the colors work. It's how GPUs calculate the scene. I might have this backwards (or completely wrong), but when you render something with a GPU, it shoots rays out from the camera, but with alpha textures it has to calculate those backwards. Which makes things slower.
I did a quick test with the smaller res texture, and it seems that having an 8k map was contributing a lot to the slow down. Good thing this is an embarrassing things thread.

The thing that's killing your performance is all that empty space in your leaf planes, the GPU is spinning it's wheels doing complex calcs for a lot of 100% transparent surface area. Trim that down and if possible use a cutout/masked transparency shader.

I'm using an alpha clip, so it shouldn't be calculating all that.
It's either on or off.
