   2 problems (Skinned Mesh and Home Designer)
  I have studied directX and C# for 2-3 months. However, I come up with two problems.1. In the skinned mesh sample, I find that it is very difficult and I fail to convert it to C# version. I have also read the sample from Tom Miller book, however, it only runs in software mode which is extremely slow. It requires MaxBlendVertices>=4 but my display card only supports 2. But, the skinned mesh sample from directX SDK runs very smoothly. Where can I find more reference on skinned mesh C# version ?Is the maxBlendVertices requirement depends on models creation? ie. when I create the models and anmination in 3D studio2. The second problem is not really related to directX. I want to include a home designer in my project. Is there any existing engine which provide and interface for moving objects ? ie. existing engine --> specific data structure --> render the home depends on the data structure. Thank you very much
