Exporting solid UV shells

HeavyMetalFox — Mon, 08 Feb 2021 20:17:14 GMT

The UV snapshot options in May are very limited, I am looking for a way to be able to export "solid" UV shells where they have on color inside of them (no wireframe) for 3d painting purposes, is there a way to do that?

What you mean by Solid UV shells?

Since you are 3d printing, how UV matters for print?

there might be a script somewhere. default Maya i don't think it is there.

However you can make each shell have a different color. But when you export UV snapshot the wire frame will be on top of the color.

how can I did you assign the colors to the shells?
And were you able to export the snapshot with the colors?

You may look for some UV scripts free at highend3d.com Maya scripts and plugins. Last time I had a app ROADKILL for Maya. I think that one does bi default. If I were you then I will look for 3rd party free scripts.

Hi!

@HeavyMetalFox and @mihirsbcc

You can't export colors with the UV Snapshot Tool.

The only option (besides taking a screenshot) is to bake the colors to a texture, for example by using

Arnold -> Utilities -> Render Selection to Textures (with Extend Edges disabled), this does produce the output as requested.

screen shots is my usual path.

when I do that I am getting a transparent EXR texture.
Can you please post a video showing your workflow?

Hi!

There will be an alpha information written with white where there is something and black where there is no color information. You could even directly use the alpha/transparency information, but when you skip this you get the color from the object + black (empty).

There are just 2 steps:

1. Select the object.

2. Render Selection to Texture

Please provide a scene-file, one step before you use Render Selection to Texture.

tried with not much success

Hi!

This works, I am 100% sure.

If it does not work for you, please provide the Maya scene-file and your EXR image file.

Hi!

Here 2 screenshots, one before baking the texture and one after baking, so this seems to be exactly what you requested.

Great and thanks alot!
Now is there a way to make the wireframe show?
I am doing this because I need this map in Unity and the UV snapshot tool in Maya generates jagged lines (even with anti AA turned on)
