bender how to export model free blender 3d

If you had to export this model with this physic model you wouldn't be able to walk through it. On the left, you have a bad example of a concave physic model. Screenshots will be easier to understand than words. Source can't handle one physic model to be used as a concave. To do so, we will need to cut our physic model into multiple parts. The player must be able to walk through it. Yet, you'll sometimes need a model where the player can walk under / through.Īs you can see in the example on your right, I made a doorway. It's more efficient and easier for Source to handle this type of collision. You will use this type of collision most of the time. What we just made is a convex physic model.

There are two types of collisions in Source. It will be explained more in the next chapter.Ĭoncave physic VS Convex physicWe will need to be a little bit more technic in this chapter. Now I have two collections, one with all part that composes my model and another which contain every part of the physic model. You must have a material assign to each part of your physic model!Īlso, you need to separate the physic model from the original model by creating a new collection.

It doesn't matter if Blender to Source doesn't export Blender materials. Just create a new Blender material and assign it to the physic model. Finnaly, all parts of the physic model must have the same materials, and they must have a materials asign.And we all know what an angry Source does! The model must have smooth shading enable! It's really for Source! If you do not smooth shade your model, Source will not like it.

It is important, your physic model must be as low poly as possible!

It's a low polycount version of the model.

You can see how I made the physic model for the wall lamp. Making a good physic model for your model is important both for render and for optimization. Physic model Now, let's work on the physic model.
