There is a post in this thread viewtopic.php?f=8&t=15240, which explains how to install this manually. Mainly it revolves around just moving the file folder with the plugin files manually.

I was not aware that the IGMESh format Indigo uses and naturally Blender exports into, supports quad meshes. Does it ?

Also, the version number referenced in this threads title does not represent the latest Blendigo version.
You can get the latest version of Blendigo 4.4.1 on GitHub:
https://github.com/glaretechnologies/blendigo

That exporter also supports the newest version of Blender 3.4!

Time to update your tool chain ;-)

I'm try

Blender 2.79 + Blendigo 4.2.2 > export Cube to Indigo 4.6.0 - 4.6.7 > Pick Object > Cube > Geometry = Num quads: 6

Blender 3.4 + Blendigo 4.4.1 > export Cube to Indigo 4.6.0 - 4.6.7 > Pick Object > Cube > Geometry = Num quads: 0


perhaps I’ll focus on version 4.2.2 in it, the quad mesh mesh on the render is amazingly smooth surfaces of highlights, and in the triangular mesh after subdivision it turns out 'saw'

4.4.1 I already managed to twist, the light and layer settings work more stable in it, but for my tasks (concept art) the correct mesh quads is preferable

I tried all versions from the repository, the latest version of Blendigo supporting mesh quads is

blendigo-4.3.0-c6e8e05-2.79.zip

unfortunately for some reason the plugin versions for Blender 2.80+ don't support mesh quads export

Check github repo. Latest version there is 4.4.1 (from Dec. 29. 2022)
https://github.com/glaretechnologies/bl ... /tag/4.4.1
Can also open 'New Issue' there.

Why do you still work with that old version of Blender?

Edit. Ahh, I see!
It worked in 4.2.2 and that is also why you are still Blender 2.79 ... hmmm...

Hi,
If I remember correctly, introduction of new dependency graph broke quad export. Exporting quads in Blender 2.79 was easy and convenient, while since Blender 2.80+ quad mesh had to be recreated from lists of vertices and edge loops, if I remember correctly. At that time I thought that it didn't make much of a difference and left quads to be done in future.

Currently, I'm working on a new material nodes system. Exporting quads along with custom normals is likely to be next in line.

I see that you used subdivision option in the Indigo Renderer. I think this is the source of the problem, because right now the exporter converts evrything into tris. Can you subdivide this mesh in Blender?

thanks ... this partially helped. except for smoothing the edges. (surprisingly, there is no information about this in the instructions of the site)


maybe you have an updated physically correct scene from the reference material (IMPmatdb-corrected-base-bump.blend) for Blender 2.8+?


the .blend source code of 2009 is outdated and not relevant
viewtopic.php?t=5333&start=30


i used this instruction
https://blender.stackexchange.com/quest ... lender-2-8



ps doesn't tri mesh increase the load on indigo? after all, tri has 2 times more polygons :?

the gradient of the shader in the tri mesh is displayed with an offset :)

Interesting, though there're too many variables to unpack. Please wait few more days for an update. Quads, custom/split normals are on the way and hopefully will fix all these issues.
