So if you're a beginner like me and you are wondering whether it's worth spending money on Cheetah3D when there is a free alternative in the form of Blender, then I'd recommend you go for it, unless of course you have a play with Blender and decide that you like it. Personally, I just find Cheetah3D more intuitive. I found that I could make progress just by choosing likely-sounding tools or options from the menu and playing with them, often with a quick read of the built-in help to clarify what some of the options do. Blender gives the impression that it has a lot of functionality, but doesn't expose it in an intuitive way. It's worth saying that just watching this one video:įrom NoVolume was enough to give me a very good start on my drill, and actually was really inspirational in showing the great results you can get with a few tools and in a short space of time, so thanks to him for posting that! Having used Cheetah3D now and made some progress with it, I think I would probably get on better with Blender if I went back to it - I'd have a better idea of what to look for in terms of tools and options, although I think I'll stick with Cheetah3D for now. Gives a 360 degree view of it, plus a nice big picture of the side view shown above, which was enough to get me some 'blueprint' images and get some kind of a view of the tricky parts. In the event, I only ended up with a nice side view, and a fairly crappy front view as my blueprints, so there are parts where I only had a sketchy idea of what it was supposed to look like and had to improvise, but on the whole it's pretty close.įun fact: if you search for images of drills you will see that almost all of them are in the orientation shown above (with the business end on the left and the handle on the right). Why is this? I can only guess it's because we live in a right-handed world and so (subconsciously) there is an expectation that the handle should be on the right. It makes me wonder if in the world of product imaging everyone knows that handheld items should be pictured oriented this way, or if they don't actually give it much thought but have all unconsciously ended up orienting them this way due to their innate right-handed bias.Unity's physics system expects 1 meter in the game world to be 1 unit in the imported file. If you prefer to model at a different scale then you can compensate for it here. defaults for different 3D packages are as follows. Increasing this value will reduce the file size of the mesh, but might introduce irregularities. It's best to turn it up as high as possible without the mesh looking too different from the uncompressed version. This is useful for optimizing game size.Įnables the mesh to be written at runtime so you can modify the data it makes a copy in memory. When this option is turned off, it saves memory since Unity can unload a copy of mesh data in the game. However, if you are scaling or instantiating meshes at runtime with a non-uniform scale, you may have to enable "Read/Write Enabled" in their import settings. The reason is that non-uniform scaling requires the mesh data to be kept in memory. Normally this is detected at build time, but when meshes are scaled or instantiated at runtime you need to set this manually. Otherwise they might not be rendered in game builds correctly. This option determines the order in which triangles will be listed in the mesh. If this is enabled, your meshes will be imported with Mesh Colliders automatically attached. Note that an inspection may be conducted before a permit is issued, in order to ensure the applicant’s facility has appropriate measures in place to minimize the accidental release of biological agents capable of causing human disease.This is useful for quickly generating a collision mesh for environment geometry, but should be avoided for geometry you will be moving.
