Using the Gamedev Texture Sheets Houdini tool, I could get normal information in the R & G channels in the texture allowing for some lighting on the sprites. However the shading was not really up to par – it’s just a normal map in the end of the day and can’t provide any real contrast. It’s pretty cheap though, using only one texture for the whole thing. This kept me wanting to push my explosions further, which I did, here!
