I absolutely am IN LOVE with SEUS shaderpack and I have been able to run it just fine with FTB. I tried this with multiple packs and when i place certain TE3 blocks such as a redstone furnace or pulverizer it is whited out and the texture of the front of it and sides spazz out. I have some screenshots below before and after shaders and i really do not want to have to get rid of shaders because i cannot see certain blocks. So far i have only seen this with TE3 blocks.
