Feature addition.
When reading in textures, please check for the presence of a file called "textures.link" or something, which contains one line such as;
g:\quake3\baseq3\textures\common
So that, when I'm reading in, lets say, my \eerie directory, it goes through and adds my textures to the palette, along with everything in common.
Don't forget to add "Finer texture alignment" to the list. I'd like to be able to move in 0.1 increments using the Shift-Arrow Keys.
No. Sometimes textures are drawn the wrong way on patches. We'd like the ability to flip a texture. Like the way X/Y scale -1 used to worked.
1) Easier way of deleting rows, columns
2) Fine tuning of textures on patches (X/Y shifts other than with the surface dialog)
2) Patch matrix transposition
1) Actually, bump texture flipping on patches to the top of the list of things to do.
2) When you select a patch, and hit S, it should read in the selected patch texture. Should not work if you multiselect patches and hit S
3) Brandon has a wierd anomoly. He fine-tunes a patch with caps. It looks fine when the patch is selected, but as soon as he escapes out, it reverts to it's pre-tuned state. When he selects the patch again, it looks tuned
*1) Flipping textures on patches
*2) When you select a patch, and hit S, it should read in the selected patch texture. Should not work if you multiselect patches and hit S
3) Easier way of deleting rows columns
*4) Thick Curves
5) Patch matrix transposition
6) Inverted cylinder capping
*7) bugs
*8) curve speed
Have a new feature request. "Compute Bounding Box" for mapobjects (md3 files). This would be used for misc_mapobject (essentially, drop in 3DS Max models into our maps)
Ok, Feature Request. Load and draw MD3's in the Camera view with proper bounding boxes. This should be off misc_model
Feature Addition: View/Hide Hint Brushes -- This should be a specific case.
