If you know how to fix it, or have something better we could use instead, please let us know: You've told us there is information missing from this page. Returns filtered pixel color at normalized coordinates (u, v). Also used cv::imwrite to save the image for testing purposes but the issue in also in the saved image. GetRawTextureData(). 3; see page 99 of the 3. My understanding is that because noise is data it should be generated and imported as a linear texture. 4 (currently in beta), will bring a much awaited feature (since 2013) that is array-textures - in the same vain as OpenGL's ArrayTexture. 1] range. If you don't import them and create sprites, those sprites do not actually exist. The array doesn't contain a copy of the data, so GetPixelData doesn't allocate any memory. Any idea or workaround ? Or maybe use regular textures, as the sphericalpanorendrer does ? Best regards Phil Jan 20, 2023 · EDIT: Are you saying that a 2D texture loaded from disk will be as fast as a 3D texture loaded from disk, and the only slow case is the render texture?
