UV set help!

SaferDan

Ive built my low poly but when i click high quality my comp goes really really slowly

Im pretty sure its because of my uv sets



is there any way around this? or how to fix it?

Ark

Make sure 'Assign shader to each projection" is unticked under the 'create UVs' menu and make sure the 'Create new uv set" is unticked in the projection windows.
You'll want to consolidate those multiple uv sets into one uv set, less it'll send the draw calls through the roof for a single asset.

SaferDan

See both of those things were unchecked!

Could you please tell me how to consolidate the UV's into one set?

Ark

Not a regular maya user, but i think you'll have to copy and paste each uv set until there all on one map, then delete the remaining uv sets. Tedious work!

SaferDan

I don't suppose you know how to do that?

Thank you for the help already though

Ark

Try the Copy and Paste functions under the UV Editor. Check the help on how to use it.

SaferDan

hang on... there are all on one map? Map 1?

If i merge the meshes then the list disappears, but i want to try and make the list disappear with all my meshes as separate if that makes sense?

Ark

Then just use the delete uv set function to get rid of the remaining uv sets.

SaferDan

i can't delete the remaining sets?

on the UV editor it only shows map 1?

i hate maya

Ark

If it only shows map 1, then that object only has one uv set. Try going through each separate object and make sure they only have one uv set each. If thats how it is now, thts fine, however when you export, you'll want to make sure that only a single shader is assigned to the objects so each piece references the same material, less you'll end up with a separate material for each object and thats not what you want.

Another way would be to combine your objects to a single object, this will also merge all your uvs to a single uv set.

Yeha its just it was properly slowing down my computer when i put it in high quality mode. Ive had this problem before but if they are all on map1 there is no way around it because they are all separate objects right?

See i didnt want to merge them all yet because i need to bake ao and normals from each separate piece?

I seem to have solved it by hiding some stuff and assigning everything to a new uvset. Im not sure what ive done but my comp isnt running slowly any more so i guess it will have to do.

so there is no way to have merged uvs with separate objects?

Thank you very much for the help though

Aslong as the objects use the same shader then you should be able to have separate objects and have them grouped in the uv editor.

ivars

You only have one UV-set (map1) but you have several objects selected, that's why that list is so long.

High Quality view is really (!) slow with multiple objects, especially if you have a big texture. Even if every object have the same material.

Try merging your objects (if you can) and you will notice an increase in performance.

Well thats a bit rubbish! Some needs to fix that! I needed all of them separate to bake normals and AO from after ive done that then ill merge it all together.

Ark what do you mean by the same shader? The same material?

ivars

yep I know, it's frustrating! but what exactly is it that you are doing that you need HQ rendering for? I would guess it's texturing, and for that you could just save another scene with it merged to work on the textures, since the UV:s would be the same.... maybe....

SaferDan

yeah the only real reason was to preview my normals after each bake, but id already test baked everything its just to be sure, a bit of OCD i guess.

but yeah like i said someone needs to fix it!
