Important: Blender being able to properly and correctly render transparent surfaces is dependent on a number of criteria including but not limited to the application itself, system graphics and/or rendering capabilities therein. For real-time, live or game-related content creation using ( Eevee Render Engine), transparency is typically achieved through use of a separate mask image, or more commonly, the alpha channel of a standard compatible RGB image (Red/Green/Blue), that is the A component (/Alpha) of a typical 24 bit RGB A image. Transparent (no alpha) areas will then show a checkered background.', but I cannot find these buttons anywhere.There are a number of ways to generate or create transparent materials in Blender. In this link it mentions in the tip ' In order to see the effects of the Erase and Add Alpha mix modes in the Image Editor, you must enable the alpha channel display by clicking the Display Alpha or the Alpha-Only button. I feel like I'm missing something obvious. I've set up a nodes 2.93.5 shader like this hoping it would work: ply file shows the vertices with the alpha set to zero: I have tried Workbench, Cycles and EEVEE as the renderers:Īn exported 2.93.5.
Here's another blueish painted plane with the bottom two vertices with Erase Alpha applied.
Trying to reproduce this in 2.93.5 doesn't work. The Renderer is set to Blender Render as per default. Note that in 2.79c I'm using the default material and have done nothing more than start Blender, added the plane mesh and then applied the vertex paint and erase alpha. ply file shows the vertices with the alpha set to zero, (the rightmost value, the 'A' of the RGBA value):
In Blender 2.79c you can see the effects of Alpha transparency using the Erase Alpha brush mode on the bottom vertices:Īn exported 2.79c. The only attribute the vertices will have is an RGBA colour. Note: The meshes are to be used in a game engine with no textures or normals etc.
I can see the alpha transparency in Blender 2.79c (nightly build) but not in 2.93.5. I'd like to use Blender 2.93.5 for modelling vertex coloured meshes but I'm unable to see the effects of Erase Alpha in vertex paint mode.
