Hey there,

So I guess this is kinda simple question- how do I fit UVW map to bitmap? In 3ds max this feature is called "Bitmap Fit" under UVW options.
Because when I use non square textures they get cropped if using box projection. So how do I fix this? Ofcourse you can try transforming/scaling image or uvw map manually but it's a pain in the ass to get it right.
Thanks!

P.S. C4D user here.

If I get you right.. you just want to project a texture without unwrapping your object?

Yeah you can try to do a box/flat project or whatever works best and then scale and move the texture. Sometimes this works, depending on your object/texture. If you want to add displacement maps later you are screwed anyway as these only work on unwrapped objects/UV projection. Best is probably to just unwrap your object properly.

If you aren't that comfortable unwrapping objects I can recommend Unfold3D. I use this all the time. It's super simple and has saved me many times. Look up some tutorials on Unfold3D on Youtube and see if its something for you.

Yes I want to project a texture without unwrapping it. And for archviz modeling I think you can get away without unwrapping like 90% of the times Simple box/flat UV maps is enough most of the time (and displacement maps works this those as well by the way).
So the only problem is that theres alot of textures I have that is non square aspect ratio (like all the wood textures often is longer than wider) but without re-scaling UV map these images gets cropped, and as I said adjusting UV's scale manually to fit the image perfectly is a pain in the ass.
Yeah I know about unfold3d and I own that, but usually I model simple things and I don't want to spend some extra time for exporting/importing things just to have my flat UV map the correct aspect ratio I want.
I really think there should be a simple way to achieve this? As I said, 3ds max has this feature I'm looking for.

And by the way, in the project texture node there is a "external transform" input which i thought would be the feature I'm looking for, but when I click it and select my image it only creates bitmap node inside the material editor. What's up with that?

Planar/Box projection and "Fit to Image" command.

Where can I find this command?

Nevermind I found it !

Though it is kinda weird that it doesn't work in cubic projection mode.
