Has the Chaos Ideas Portal been dropped? Whenever I go there I get 404 error and it’s been like this for a while now.
If that’s the case, is there any new place where users can vote for features and monitor the current status of the requests?
Yes, it is. All the ideas were transferred to the “Requests” subcategories in the forum, so use them instead.
Yup, just use the relevant Requests category, as explained, for example, here:
V-Ray for 3ds Max - About the V-Ray for 3ds Max Requests category
Corona for 3ds Max - Updates to the Ideas and Feature Request process for Corona for 3ds Max
