Custom Texture In Gimp

[Calena]

Next, I'll change the opacity of the Brick layer to allow me to see both images overlayed. Then I'll use the lasso mask tool to create a mask around the bricks where I'd like to cut them out. (Disclosure: I'm doing this really fast to create these screen prints. I'm usually much more careful than this :



Once I have my mask, I'll use the eraser tool to erase the bricks in that area, letting the gears show through. I can now work with the graphic at full opacity again.



At this point, I need to soften the edges of the bricks plus I want some shading to create a sense of depth from the bricks to the gears. I'm going to use the Filter Drop Shadow function to do this. I'll invert my mask that I used to erase the bricks so that it now masks the remaining bricks and create two drop shadow layers, each going in a different direction. Once those are in place, I'll again invert my mask and open the Wall Cracks image as a NEW LAYER. I will use the eraser tool to erase the cracks inside the mask; don't need the cracks on the gears :



The final layer is the dirt on the walls. I repeat the process I used with the wall cracks, opening the dirt decal as another NEW LAYER and erasing the dirt inside the mask:



After I've erased all the dirt from the mask area, I'm ready to finish the new graphic off. I'll merge the visible layers into a single layer and in this case, I'll also remove the alpha layer, since it isn't needed for the scene.

I'll scale the image to the size I want it (512 x 512 here) and export as a .png image. I prefer to use .png images rather than .jpg images because .png is a lossless format. The final image that I put in the age I'm working on:
