Corona bitmap in Background

[CharlyRT]

Hi
I noticed that Corona Bitmap doesnt display correctly in background viewport while 3ds Max bitmap does it, dont know if theres something wrong with my bitmap or file or is a bug
I attach both Bitmaps properties

Which version of Corona did you use here? I couldn't reproduce it. Please let me know if I am doing something wrong.
Max 2025, Corona 13

Hi Marcin
I totally forgot to mention that Im using Max 2026.1 with Corona 13 but I remember that I had it in previous versions too.
I dont think youre doing something wrong, its the map resolution, Im testing with half pixels and its displaying correctly.
The map has 3200x3000 px, hope this is this not a Corona bitmap limitation?
Another annoying thing that I noticed is that every time I connect a Bitmap in background the Enviroment resets to spherical type, is this something from 3ds Max?

Sorry, I didn't get this part. So is there some problem or not? What exactly is happening?

You mean a Max Bitmap, right? In that case, it's 3ds Max, not us.

Sorry for the confusion.
Yes theres is a problem, but not as I mentioned, its not a resolution issue, its how you insert the texture in environment background.
If you configure the tiling before connecting to environment map, the image is wrong displayed.
But if you insert the image first and then adjust tiling, everything works ok.
This doesnt happen with 3ds max Bitmap.
I couldnt attach the video sample, so heres the link

Thank you for all the details! What a bizarre bug. It is now reported as (Report ID=CMAX-1745).
