Remarks
Locks an RHI texture's mip-map for read/write operations on the CPU pointer to the CPU accessible resource data
Parameters
| Name | Description |
|---|---|
| Texture | the RHI texture resource to lock, must not be 0 |
| MipIndex | index of the mip level to lock |
| LockMode | Whether to lock the texture read-only instead of write-only |
| DestStride | output to retrieve the textures row stride (pitch) |
| bLockWithinMiptail | for platforms that support packed miptails allow locking of individual mip levels within the miptail |
