The description of gles spec is that GL_R8
texture is supported as renderbuffer, but attach fbo fails in practical applications, Has anyone else encountered a similar problem?
No. GL_R8
textures are supported as texture attachments, and GL_R8
renderbuffers are supported as renderbuffer attachments.
That said, the GLES 3.0 spec does require: 1) GL_R8
to be a color-renderable format, as well as 2) support for both GL_R8
textures and renderbuffers.
- Is it a texture or a renderbuffer?
- Are you calling
glFramebufferTexture2D()
orglFramebufferRenderbuffer()
- Have you double-checked the arguments?
- Do you have the FBO bound?
- Which GL error are you getting?
- Let’s see your code (FBO creation, texture or renderbuffer creation, FBO bind, and FBO attachment call)
