Join Brian Bradley for an in-depth discussion in this video 3ds Max bugs that you may need to work around, part of 3ds Max: Substance to Arnold.
- [Narrator] In this video, I just want to brief you on a couple of bugs in the 3ds Max material editor that you will probably run into as you work through this course. Especially so, if you were using scene files that are being saved as you go, be that from the initial start scene provided with the course or from completely new scenes of your own. Now to be clear, although I will be demonstrating these bugs using 3ds Max scene files from the course, the idea isn't for you to open these files at this point as you will ultimately just run into a bunch of other issues with assets and files that you won't yet have created.
The first book and one that will affect you no matter which way you work through the course comes when using the bitmap material substance node in the Max material editor. On screen here, I have the scene file from chapter two and video three open which has the bitmap material substance node loaded into the scene and it has its connected material applied to the ground geometry. Now, because I have saved and reopened the scene, we can see that something is clearly broken as the ground geometry is black.
And if we jump into the ground tap in the material editor, you can see that the input bitmap followed the bitmap material to node has disconnected itself. Indeed, watch what happens if I double click to refresh the substance node which gets the inputs to show up again. Pipe the bitmap image back into the input slot and then go ahead and save again. After which, I can reopen the scene file.
As you can see, even after saving the changes, the input bitmap for the bitmap material node has again disconnected itself. Now, this will happen with every scene file in the course that has this ground substance applied to the ground geometry, which unfortunately happens to be pretty much all of the 3ds Max scenes. This, in turn, means that for each scene file you open as you work through the course, be this those provided in the exercise files download or even scenes of your own that you save as you go, you will need to run through the reconnection procedure that I have just demonstrated.
Again, this will happen with every scene file for the course that has this ground substance applied. Another bug that you could run into depending on how closely you follow the steps that I take in the course is that of disappearing materials. At certain points in chapter four, I will be using the Move Tree to View command from inside the slate material editor. Which I have unfortunately found upon opening the scene that was saved after taking this step can cause the annulled material setting at the top of the text to chain to disappear.
Now, the good news is that so long as that material tree was applied to an object in the scene, then all we need to do to recover it is clear out any leftover nodes from the material view being used and then use the pick material from object tool to repopulate the view. Just be sure not to clear out any free-standing nodes that we may be making you solve elsewhere in the scene, such as in a displacement modifier. If we then go ahead and save the scene again, the offending material shouldn't cause any further problems.
So the provided scene files for this course, for instance, shouldn't exhibit this behavior. But, if you are saving and then opening work using your own scene files as you go than you may well have to imply this little work-around.
