Merged goto01 and reworked some code.

Implemented the texture scaler provided by goto01 (Kiryl Tkachou) and removed the old ones. Implmented the mesh export bugfixes. Changed mesh export names. Changed texture export names. Updated the the export window. Updated export functionality. Updated hotkeys. Fixed quad duplication bug. Minor visual changes. Co-Authored-By: Kiryl Tkachou <goto01@users.noreply.github.com>

 Texture atlas creator for Unity

-You can combine textures and/or remap the UV’s for the 3D models.
-By having full control over the size and position of the textures that are being placed in the atlas you will never stand for surprises when exporting. This will cost some more time than auto-generating your texture atlases but you know whats going on and which models/textures are getting priority.

+By having full control over the size and position of the textures that are being placed in the atlas you will never stand for surprises when exporting. This will cost some more time than auto-generating your texture atlases but you know whats going on and which models/textures are getting priority. The tool can also be used to make 2D sprite sheets.
+
+- Combine textures/sprites.
+- Automatically adjusts the UV's of the assigned meshes to match the new texture atlas.
+- Exports meshes as OBJ.
+- Exports texture atlas as PNG.
+- Exports texture atlas as a (sliced) sprite sheet.

Author	SHA1	Message	Date
max	e81a4ec119	Merged goto01 and reworked some code. Implemented the texture scaler provided by goto01 (Kiryl Tkachou) and removed the old ones. Implmented the mesh export bugfixes. Changed mesh export names. Changed texture export names. Updated the the export window. Updated export functionality. Updated hotkeys. Fixed quad duplication bug. Minor visual changes. Co-Authored-By: Kiryl Tkachou <goto01@users.noreply.github.com>	2019-08-30 01:11:33 +02:00
Max Kruf	26a0f68454	Merge pull request #1 from goto01/master Adding the scaling and export options. Merging the changes made. Sub-meshes export bug-fix. Export window changes. New texture scaling function. (TODO: some old code cleanup.)	2019-08-29 18:56:01 +02:00

max	7f17793af0	Fixed gray texture on export. Fixed gray texture on export bug, it was caused by the texture scale function (during upscaling), right now it's required to have the texture dimensions be a power of 2 width/height. Optional OBJ/PNG/sprite export options. Chanaged readme. TODO: Cleanup export code. Make proper scale options (bilinear & point).	2019-07-16 14:12:32 +02:00
Max Kruf	09f7c488b9	Update README.md	2019-07-04 23:22:57 +02:00
