If you have not been able to find a 3D model, try this website. The models are completely free. Obviously, there are better and worse models. You download the models in the *skpl extension, but you can merge them to 3ds Max. However, pay attention to correct polygons and the grid. Sometimes they require correction. Do not download poor models. Instead of speeding up your work, they can actually make it much more difficult.
This is the most popular website with 3D models and probably with some of the best models. Each day you will get 3 models for free after logging in. And for just a couple of dollars or for 18$ per month you will get PRO models.
On this website, under the FREEBIES tab, you will find a few interesting items. You can download the Models in several extensions with materials for Corona and Vray. You can download free models without any limitations.
Here you will find models at prices ranging between a few dollars and 12 dollars. There is also the FREE tab with some interesting models. It is worth signing up for the newsletter as Bentanji often introduces 30-50% promotions.
This is one of our favourite websites. Here, you will find both paid and free 3D Models. After registration, each day there will be 3 models for free.
3D models have recently been made available on our website. As time goes by, there will be more and more of them. We plan to introduce models which will make your scenes more beautiful and also those which are hard to come by. If you have any idea for a 3D model, write to us. We will gladly find out what you are missing. For now, there are only FREE Models.
