SOLVED Cinema4D Get Texture Atlas/Get Image At Coordinate

Hello there I am wondering how I can use a texture atlas in cinema4D to use for my icons instead of loading seperate icons for example like what I see they are doing in XPaticles

Did GetClonePart and it works 🙂

Hi,

it is a bit unclear to me, what your actual question is. The bitmap type of Cinema is BaseBitmap. It has a method called CopyPartTo with which you can copy a part of a BaseBitmap (your atlas) into another BaseBitmap (an icon). There is no texture atlas type in the Python API for Cinema, which would handle the parsing of an atlas and its metadata into a set of bitmaps for you. So you will have to do that yourself.

Cheers,
zipit

@zipit said in Cinema4D read texture atlas:

e

Seems like you might have answered the question I wanted to know how to get the icon I wanted from that image and use it as an icon in C4D seems like GetClonePart returns the bitmap CopyPartTo returns bool is CopyPartTo still the anwser?

Did GetClonePart and it works 🙂
