Texture backface flip #8

Closed andrewtheone closed 8 years ago

andrewtheone commented 8 years ago

Hey!

Me again, I tried to solve this one on my own, but just cant figure it out. Problem:

I give only 1 texture to a voxel. It displays perfectly. (I'm only interested in the side-faces (front, left, right, back, .... bottom and top doesnt matter). 3 out of 4 faces displays correctly but the back one is fliped vertically, any idea how to get rid of this?

Weird, I haven't touched that code in a looong time. Is this with the vanilla engine, or did you tweak anything in the rendering or chunking code? If it's the standard engine, can it be minimally reproduced?

andrewtheone commented 8 years ago

its fully vanilla part

reproduction: take a image, with some text on it (so it'll be easier to ditinquish if its flipped and if so in which direction)

register material, pass image as texture

place a block with the texted texture, walk around and up and down

Hmm.. I see stuff horizontally flipped (2/4 sides) but not vertically.

Does this happen in the testbed? E.g. for the "grassy dirt" blocks, is one of the sides rendering for you with the grass on the bottom? If so, can I have OS/browser/version details?

No, i does not happen in the testbed

I meant to say "on Y axis" when i said vertically, so yeah, if you stand in front of a block, whats on the right side on the front, that goes onto that left side on the backside of the block.. -if it makes any sense-

I get you know, and this is fixed by 26b5ba6.

Thanks!
