When I set the transparency of a bitmap in the viewport with BaseDraw.SetTransparency with a value below 50 (25% in the 0-255 range), and draw the bitmap with BaseDraw.DrawTexture with the alphamode set to DRAW_ALPHA_NORMAL or DRAW_ALPHA_FROM_IMAGE, the bitmaps disappears.
If the alphamode is set to DRAW_ALPHA_NONE, everything works fine.
Is this a limitation or a bug?

Hello,
could you provide some code that shows what exactly you are doing and that would help us to reproduce the issue?
Best wishes,

Using this code, I get smooth transparencies from 0 to 255:
bd.SetTransparency(-trans)
padr=[c4d.Vector(x,y,0),c4d.Vector(x+w,y,0),c4d.Vector(x+w,y+h,0),c4d.Vector(x,y+h,0)]
cadr=[c4d.Vector(1,1,1),c4d.Vector(1,1,1),c4d.Vector(1,1,1),c4d.Vector(1,1,1)]
nadr=[c4d.Vector(0,0,-1),c4d.Vector(0,0,-1),c4d.Vector(0,0,-1),c4d.Vector(0,0,-1)]
uvadr=[c4d.Vector(0,0,0),c4d.Vector(1,0,0),c4d.Vector(1,1,0),c4d.Vector(0,1,0)]
bd.DrawTexture(image,padr,cadr,nadr,uvadr,4,c4d.DRAW_ALPHA_NONE,c4d.DRAW_TEXTUREFLAGS_INTERPOLATION_LINEAR)
But with this code, as soon as the transparency is set to 50 or below, the drawn image simply disapears.
bd.SetTransparency(-trans)
padr=[c4d.Vector(x,y,0),c4d.Vector(x+w,y,0),c4d.Vector(x+w,y+h,0),c4d.Vector(x,y+h,0)]
cadr=[c4d.Vector(1,1,1),c4d.Vector(1,1,1),c4d.Vector(1,1,1),c4d.Vector(1,1,1)]
nadr=[c4d.Vector(0,0,-1),c4d.Vector(0,0,-1),c4d.Vector(0,0,-1),c4d.Vector(0,0,-1)]
uvadr=[c4d.Vector(0,0,0),c4d.Vector(1,0,0),c4d.Vector(1,1,0),c4d.Vector(0,1,0)]
bd.DrawTexture(image,padr,cadr,nadr,uvadr,4,c4d.DRAW_ALPHA_NORMAL,c4d.DRAW_TEXTUREFLAGS_INTERPOLATION_LINEAR)
