misc VR-related notes

how to see how many draw calls I have

there's this thing called "draw calls" that it is best to minimize when making 3d shit.

I haven't figured out exactly how to minimize these properly.

it was annoying trying to figure out how to even see how many.

I am currently checking how many by going into some world on

hyperfy

and then dragging and dropping my avatar into it.

side note. since I don't use a graphical file manager, I had to find some way of dragging and dropping a file into my browser window.

for this I'm using some random thing I found on the internet called dragon and I probably should have read its source code before using it.

https://github.com/mwh/dragon

I need to figure out why bash doesn't autocomplete filenames for dragon... really annoying.

So drag your avatar in, then click the circle on the top-right of the "window" that pops up.

in my unoptimized avatar, it is a red circle. after clicking it gives some handy info.

[img] the info

file size, triangles, draw calls, bones, and bounds.

I don't know why it is saying it has zero bones.

how to do one of the drawcall optimizations as seen on stackoverflow

https://stackoverflow.com/questions/50220930/mesh-uses-too-many-draw-calls

Found this when trying to figure out how to lower the amount of draw calls in my avatar.

Took me longer than it should have to figure out this:

go into edit mode.. select all your faces, then use the Mesh->Sort Elements->Material

So I opened blender, went into edit mode, did "select all" and the Mesh menu was nowhere to be found.

eventually I figured out I needed to go into object mode, then select a piece of mesh.

When I had opened the file, a bone was selected.

after selecting the mesh and going back into edit mode, the mesh menu was kind of obvious.

So the exact steps I've been doing:

1. object mode.

2. click on the head flesh.

3. select all.

4. edit mode.

5. select all.

6. mesh -> sort elements -> material

but this doesn't seem to work right because I expect I need to have all of the pieces use the same single material

and for some reason selecting all of the pieces at once and setting a material doesn't work how I'd hope.
