Issue description
Creating 3D textures in Cocos (3.8.8) works fine, but uploading fails because the gfx layer "wants" to upload them as texture_2d_array. I'm not sure if this is a typo or intentional... possibly for WebGL 1 compatibility? However, WebGL 1 doesn't support texture_2d_array either, and sampler3D cannot be used in shaders, so this is almost certainly a BUG. I'm not sure if the official team has other considerations.
This BUG currently causes all 3D texture related operations to fail. For example, device.copyBuffersToTexture([data], this._texture, [region]);: if this._texture was created with TextureType.TEX3D, this operation will definitely fail (no error is reported, but the data is not submitted to the GPU).
Relevant error log output
No response
Steps to reproduce
const device = deviceManager.gfxDevice;
this._texture = device.createTexture(new TextureInfo(
TextureType.TEX3D,
TextureUsageBit.SAMPLED | TextureUsageBit.TRANSFER_DST,
Format.R8,
this._width,
this._height,
TextureFlagBit.NONE,
1,
1,
SampleCount.X1,
this._depth,
));
const region = new BufferTextureCopy(
0, 0, 0,
new Offset(0, 0, 0),
new Extent(this._width, this._height, this._depth),
new TextureSubresLayers(0, 0, 1),
);
device.copyBuffersToTexture([pixels], this._texture, [region]); // wont work
