3D Realisation – Issue with TGA Bitmaps

Whilst working with 3DS Max, I came across an issue with using Targa (TGA) bitmaps as materials. When I applied these images to my model, they appeared to be very washed out and incredibly bright.

After I did a little bit of research, I learned that the reason that this happens is because 3DS max is trying to apply alpha to the model. As the images I was using is not transparent, this caused the material to appear very washed out/bright.

To fix this, when applying a TGA file to a model, you need to set the “Alpha Source” option within the material to None (Opaque). This makes the material appear normally.
