Change MRM Distance setup.
Only for mesh which support MRM. NB MeshMultiLod apply it only on Lod0 (if Lod0 is a MRM). NB: This apply to the shape direclty!! ie All instances using same shape will be affected NB: no-op if distanceFinest<0, distanceMiddle<=distanceFinest or if distanceCoarsest<=distanceMiddle. -
Parameters:
-
| distanceFinest |
The MRM has its max faces when dist<=distanceFinest. |
| distanceMiddle |
The MRM has 50% of its faces at dist==distanceMiddle. |
| distanceCoarsest |
The MRM has faces/Divisor (ie near 0) when dist>=distanceCoarsest. |

if true, the instance is said in "AsyncTextureMode".
Ie user must fill AsyncTextures field with name of the textures to load. At each startAsyncTextureLoading(), the system start to load async them. Then, isAsyncTextureReady() should be test each frame, to know if loading has completed. By default, AsyncTextureMode=false. When it swap from false to true, each texture file in Materials are replaced with "blank.tga", and true fileNames are copied into AsyncTextures. When it swap from true to false, the inverse is applied. NB: calling enableAsyncTextureMode(true) calls setAsyncTextureDirty(true)

return true if all the async textures of the instances are uploaded.
if was not ready before, this swap the upload textures into the rendered ones so they are rendered return always true if not in async texture mode, or if startAsyncTextureLoading() has not been called since last enableAsyncTextureMode(true)

Change Max Display distance.
After this distance the shape won't be displayed. setting <0 means -1 and so means DistMax = infinite (default in meshs but multilod meshes). NB: This apply to the shape direclty!! ie All instances using same shape will be affected
Note: If the instance is skinned/sticked to a skeleton, this setup is not taken into account. But you can call USkeleton::setShapeDistMax() to have same effect.
Note (complex): All instances of the same shape which are freezeHRC()-ed and are linked to the QuadGridClipManager (ie not linked to a cluster) may not be updated corretcly. In other words, you should setup this value only at beginning of program, just after creating your instance (more exactly before UScene::render()), and all instances of the same shape should be setuped with same value (or don't call setShapeDistMax() for subsequent instances). If you don't do this, QuadGridClipManager may clip such instances nearer than they should
