EDIT: TO clarify: all my textures are natively 32 bit 4 channnel RGBA obne byte per channel textures in either PNG or TGA. ASTC_10x10: ASTC compressed RGB(A) texture format, 10x10 block size. Apply();)… Compressed one channel (R) texture format. This is mostly useful for loading compressed texture format data into a texture. mainTexture. R8, false, false, image); Note that the texture arrives in the YUV format I420—creating it in the R8 format will not allow it to be displayed correctly, but for now that’s okay; I just Mar 14, 2016 · So if I build a Texture2D at runtime I have texture format options but how can I guess the correct compression format for the current platform? In the editor you have automatic compressed so in code something like GetCompressionFormat(bool alphaSupport) would be useful. It is also possible to create a texture in Unity and get a pointer to the underlying platform representation; see Texture. The following shader example samples a texture array using object space vertex positions as coordinates: 3 days ago · Note that RGBA32 format might be slightly more efficient as the data layout in memory more closely matches what the graphics APIs expect. It is possible to use NPOT (non-power of two) Texture sizes with Unity. Texture. // to the renderer's material. x, (int)sprite. RGB565: A 16 bit color texture format. GetRawTextureData: Get raw data from a texture. I presume this isn’t intentional, since the texture seems to always end up compressed which renders LoadImage quite useless for a wide category of uses. When you use ConvertTexture, Unity does the following: Creates a temporary RenderTexture that matches the size and format of the dst texture. material. { void Start() { // Create a new alpha-only texture and assign it. I know about getting the TextureImporter and the GetPlatformTextureSettings and SetPlatformTextureSettings methods. BC6H: HDR compressed color texture format. jpg file, but when I try load . JPEG for example uses a complex compression method that would make it far too slow to decode on the fly. What I’m trying to achieve is shown in the following image where the green rectangle (layer1) is centered on top of the black rectangle (layer0) and results in the image shown. EncodeToPNG: Encodes this texture into PNG format. For RGB (without alpha) textures, DXT1 is better. isReadable: Returns true if the Read/Write Enabled checkbox was checked when the texture was imported; otherwise returns false. Length, textures[0]. streamingMipmapUploadCount: How many times has a Texture been uploaded due to Texture mipmap streaming. GetRawTextureData and expect 4 byte pixels. cuwu prcgk ixmnb gdd gezd ydri ffbsfzf nyd qrczdpvr usadx
