A) Defect in texture is inherited from parent stone block.
1) Stone Block texture fix: Inverting the texture (left edge remains on left but top edge become bottom edge) for E - W & S faces of stone block. *Note lower face is already inverted image of upper face.
B) Stairs texture is both direction and upper/lower dependent:
1) North facing stair in lower position: use North face on vertical stair surface and the lower face texture on stairs in lower position.
2) East facing stairs in upper position: Use east face on interior stairs vertical surface user upper face on interior face (horizontal/tread)
This would be best solution without making E & W facing blocks 90 degrees different in texture orientation from N & S block pairs.
Proposed Solution:
Top of lower step (tread) should use image map from bottom face of block not the top.
side of upper step (riser) should likewise use the opposite side image map to that which is currently used.
Q.E.D.
Note: this also applies to stone_slabs in the bottom position the bottom image should also be on the top.
General rule for partial block patterns:
The full, exterior face pattern should show through (the solid half-section) as the interior, parallel face.
the issue that mine was llinked to is very different from the one thats happening to me. the game is running, the screen is just pure red.
