After Effects error: AE_OpenGL: A texture in this composition is too small to render.
Message interpretation:
A layer in the composition does not cover enough pixels to generate a texture from it.
Possible causes:
Even though textures for
OpenGL (your 3D layers’ pixel data) can have any arbitrary size, internally the layers will often be filled with empty pixels (black or transparent), to bring them up to a specific ratio and resolution. This increases efficiency of transform and shading calculations on some hardware and should actually completely avoid the error discussed here. However, there are some operations that potentially never generate enough opaque pixels, so the algorithm has no starting point. This can happen with very fine text, thin strokes or effects that render fine lines and dots at the sub-pixel level (lensflares, particle systems).
Resolution or workaround:
Adjust the font size of text layers or choose a font that doesn’t fade away. Likewise, increase the values on critical parameters to boost opacity of critical items. For other layers, applying additional effects that manipulate the intensity of pixels such as e.g.
Levels might offer a solution.
