Baking textures creates jagged edges Nov. 25, 2018, 4:33 a.m.

I made some progress… It is do do with using PNG format.
If I open the .rat file in MPlay, I can look at the different image planes

If I go to “bascolor” plane, and save as PNG and switch on “Convert to Image Format's Colorspace”, then actually all the extra pixels around each texture around the border of the textures get remove. Even though I set Alpha=none in Mplay export settings, it seems there is still an alpha being applied. This is a little confusing why this is happening.

If in MPlay export I switch off the “Convert to Image Format's Colorspace”, then the extra pixels are kept, and as a result, when the textures are applied to the model, there are no more jagged edges.

I am assuming that when the “Bake Texture” node exports these textures, it is also automatically converting to the PNG colorspace, resulting in the jagged edges.

Another solution is to use JPG instead of PNG, which also solves the problem… the “Bake Texture” node then exports the correct image for texturing.

Baking textures creates jagged edges Nov. 24, 2018, 3:36 a.m.

I am baking some textures using the “Bake Texture” node.

The problem is that I get textures with very jagged edges. Also, it looks like the jagged edges have no opacity (i.e. I can see through to what is behind). I have not set any opacity.

I thought that I could by setting additional pixels at border…

Or by setting anti-aliasing…

But neither seems to solve the problem.

Any suggestions?

What is the proper way to duplicate nodes as instances/references. Nov. 14, 2018, 1:08 a.m.

As pezetko said, HDA is the way to do this. HDA stands for Houdini Digital Asset.

You right click your subnet and select “Create Digital Asset”.

You instance your Digital Asset multiple times in your network.

Then if you need to edit it, you right click any of them and select “Allow editing of contents”, then edit it, and then right click again and “Save node type”.

All instances will then be updated. In all files that use this Digital Asset.
