I'm using render texture as an array of textures by specifying the size of the array in volume depth property. But, sometimes when I exceed some value (eg. for 128x128 textures it's 45...) it return me an error : D3D11: Failed to create RenderTexture (128 x 128 fmt 39 aa 1), error 0x80070057 which isn't very clear. Therefore, I supposed it's because this property has a maximum value ? But I did not find it in unity manual either on internet.

Does anyone know this value or could tell me where I could find it ?

CodePudding user response：

The width, height, and depth must be equal to or less than D3D11_REQ_TEXTURE3D_U_V_OR_W_DIMENSION (2048).

Likely you are having issues with some other parameter. Try enabling the Direct3D Debug Device for better information. Use -force-d3d11-debug. With Windows 10 or Windows 11, you have to install it by enabling the Windows optional feature Graphics Tools.
