Use this codematerial preset_1_maneMat{ technique { pass { ambient 2.0 2.0 2.0 cull_hardware none cull_software none scene_blend alpha_blend alpha_rejection greater_equal 250 texture_unit { texture preset_1mane.png } } }}also try using GIMP or something other than Sai if the problem still is happening.
When using SAI, you need to erase the white, you can also use the transparent tool.You'll need to export it as a .png and when the 2 option things come up, click the bottom one.
I used to have this problem very often, but I now use a different PNG file of the mane I came across while browsing the internet. Would you like me to create a link for you to download this PNG and see if the blocks go away?
