Gringo6... Here's a link to ( for me) the best editor when used with Photoshop. I use this program to open my ac bmp,whether it is a texture or a panel bmp. Once it shows on this programs screen,I remember what format it is in by the description shown at the top of the screen. Then in the top tool bar,I click on SEND TO EDITOR... (you assign an editor such as Photoshop in the preferences section of the program). Once the bmp is in Photoshop,I look at the IMAGE drop down menu,and see what format it is,..ie., Indexed,16 bit BMP or 32 bit BMP. It is almost ALWAYS either Index or 8 bit. If it is Index,I convert it right there to BMP and begin editing. Once I finish,I click on the IMAGE drop down menu again,click to turn it back into Index. Then,I go to the Layer drop down menu on the tool bar,and click Flatten Layers. Then,I click on File drop down and click Save. You can then leave Photoshop. Return to the DXT program,click on the menu bar to reload the image,and save it in it's original format. Sounds a little complicated,but,if you take it step by step,and use a little common sense ( no insult intended...the common sense I speak of is," If I do this,what will happen"), it becomes rather easy and self explanatory. It really is easier than it sounds. Once you get the hang of it,you'll be modifying all sorts of BMPs for your ac textures and panels. I'll be happy to continue to try and explain further it you need me. Down load this program. It is indispensable for sim editing.// //
