Every time I change random seed, the material image changes accordingly. I want to output the corresponding base color map image, what should I do?
thanks for the reply 
I MAKE MAPS WITH CUBES
AND THEN YOU CAN PUT THAT ON THERE
OR WHEN THE LEVEL SPAWNS , AT THE TOP OF THE VIEWPORT CHECK THOSE TAB ICONS AND FIND THE LEVEL BLUEPRINT IF YOU DON’T KNOW WHAT THAT IS
YOU CAN SET THE MESH FOR THE CUBE THAT YOU USED IN THERE USING " SET MATERIAL "
BUT THAT’S GOING TO BE DISTORTED
YOU CAN MAKE MULTIPLE SMALL CUBES OR MAYBE FOR THAT MATERIAL TEXTURE YOU COULD PUT THAT ON A 75 X 75 CUBE AND THATS NOT THAT SMALL
MAYBE BIGGER , I DONT KNOW
AND THEN YOU PUT IT ON ALL THE BLOCKS
THERE ARE A NUMBER OF ROCKS ON THAT MATERIAL TEXTURE
