The scene clean-up tool will identify things in the scene that will likely cause issues in the conversion process.
Note: Running the scene clean-up process can take a few minutes depending on the size of your scene. You will likely need to run the tool multiple times to address all issues. As a layer will only list one issue at a time and it is possible for a layer to have multiple issues.
Below is a list of solutions to issues picked up by the scene clean-up tool.
Proxy
Proxy
Proxy objects are not an editable poly and are not supported by this process. See below how to convert proxys to an editable poly:
Vray Proxy:
Vray Proxy:
Select your vray proxy, locate the Proxy Params and change the the Preview type to: show whole mesh.
This will show the proxy as a mesh which then can be forcefully changed to an editable polygon by adding a modifier and collapsing the mesh.
Corona Proxy:
Corona Proxy:
Similar to Vray, locate the Viewport display to change the method to "Full mesh" . Next, forcefully change the mesh or press the "Duplicate to mesh" button so it can create a second version of the plant which can be used instead of the proxy.
Un-collapsed Editable Poly
Un-collapsed Editable Poly
How to collapse object/s:
Select one or multiple objects you want to collapse
Right click anywhere on the modifier stack window and press 'Collapse All'
Scatter
Scatter
Note: As the goal is to transform all proxies into editable polygons you may want to consider reducing the number of proxies being produced. A higher number of objects/polygons will take longer to optimize/unwrap and will add to the performance budget of the scene.
Chaos Scatter
Chaos Scatter
Select the Chaos scatter (this links to all your vegetation)
Locate the Display & Limits section in the modifier stack and change the 'Previz type' to Full
Create a new layer for every plants/trees to maintain structure. Move your Chaos scatterer into the new layer. In the example below it will move from "Original Tree" to the new layer created called "New_Trees_001".
If you have multiple plants/trees on the one scatter then it is advised to create multiple layers. Each layer will contain the single proxy since these will be the location of all the instances
Select the scatterer, open the Surface Scattering tab and navigate to the bottom of the tab to the 'Instance editor' section. Press the "Convert to Max Geometry" to instance all your plants into your newly created layers.
Once the scatter are instanced into separate layers, delete the original model and the chaos scatterer as it's no longer required.
Forest Pro
Forest Pro
Note: You may have far more instances than your computer or the final output can handle - try prioritising plants/trees and use a grass texture to imitate the ground. Billboarding vegetation will change a converted model from 200k to 100 triangles, however it can also accumulate quickly when you have more than a thousand proxies and every layer requires a bake.
You can also bundle your vegetation into layers to help divide the baking time into chunks.

Irregular Scale or Rotation
Irregular Scale or Rotation
We recommend using an x-form modifier to reset the scale and rotation of objects. The process below avoids specific errors, by placing a clean 'Edit Poly' in the stack first and collapsing before adding the X-Form.
Select All Objects
Add 'Edit Poly'
Right Click - Collapse All (This places a 'clean' Edit Poly on top)
'Reset XForm' either via the modifier search or from Utilities Menu
Right Click in the Modifier Stack window and press 'Collapse All' to convert it to an editable poly.
All selected objects now have clean Edit Poly with scale reset to 100%.
Group
Group
All groups must be flattened (ungrouped). This can be done via the group tab located in the top left corner in 3ds max.
Either of the following will resolve this issue:
Group > Close
Group > Explode
No Material
No Material
Resolving all reports of 'no material' is not a requirement. We identify when this is the case to help you consider your final output. The Enviz Pro default will show a white colour if no material is applied. Apply a material if you do not want this to be the case.
Missing Plugin
Missing Plugin
If there is a modifier on a specific object that requires a specific plugin we identify this for you. As we collapse the modifier stack during this process we recommend removing it and observing the difference to see how your model changes.
