Because most of the tools I use in my workout to make planets like those : Is based on equirectangular maps , also Nasa source images are like so , I would like to find a tool or a workflow to turn dual paraboloid into rectangular, rework and then turn back to dual paraboloid. If no tools are available, which to me seems…
I’m going to guess… yes. But what software are you using? Houdini likely can do this. Substance Designer probably too. Blender could also, if you bake from a dual-paraboloid uv layout into an equirectangular one.
Every 3d package texture baker could bake from one UV to another or from one mesh to another. Could be done both ways actually. I don't use 3d max for a decade already but as far as I remember it could be perfectly done in render-to-texture dialog.Or any texture baker that support a texture on "hires" mesh. Substance…
Why re-bake to UV2? . This UV1 is the most efficient use of texture space and geometry for both spheres and sky domes . I do it same way for decades. it could lod up to cube like shape, basically a subdivided cube with a seam along equator , have proper distribution of texel size , mips properly etc. just calculate how…
It's pretty easy to bake in Max, if that's what you have or prefer. * Select the model with two UV channels on it (like my glTF example). * In the Material Editor, add a Bitmap node, and load your equirect map. * Set the map channel in the Bitmap node to the equirect UV layout (channel 2 in my example). * Add a Physical…
thankyou , what I usually do to correct distortion at poles when I work on equirectangular maps is to use hugin then I shift poles , export map , work on poles in z projection , reimport and redistort to equirectangular then I stich to original equirectangular. But I am not expert with this tool so I dunno how to adapt to…
Ok to be more specific in what I want to do , those ( not the one I posted ) are basically low resolution color maps from game starfield, I only have avilable a sea mask a surface mask ( dunno what's for ) and a color map for the biomes, so I know basically the sea and the color of the planet, I want to reconstruct the…
