Error creating bitmap 3dmax

error creating bitmap 3dmax

Just hold the SHIFT key while dragging the bitmap/map into Material Editor. A textureMap supported by your active renderer (Bitmap, CoronaBitmap, etc.). In this video, we will deal with the error message "Unsupported Bitmap Image File" when trying to use a.bmp file format inside 3DS Max. This happens because some or all of the materials in the.MAX scene have textures applied to them which are pointing to invalid bitmap paths. Solution: To fix.

Missing Maps Error Using Arnold

These days, most users are applying their materials through the Revit models, assigning them directly to the families. This is necessary when rendering directly in Revit and is quite useful as well when using software like Enscape or Twinmotion. It is also very useful when importing a model into 3ds Max but here is where a slight problem occurs.

In this example, I’ll import the Residential_Sample_Project.rvt directly into 3ds Max. The materials imported from Revit are all the old Autodesk Pro materials from ages ago and they do not render well in Arnold. It does not matter if you import directly or export the file first to FBX from within Revit, the results will be the same.

Upgrading the materials is quick and easy using Scene Converter, found under the Rendering pull down menu. Once the upgrade is complete, you go to render the file only to be greeted with an aborted render with errors. The cause of this is missing maps, as noted in the error dialog. I’ve tried altering the Scene Converter preset to delete missing maps, but this does not seem to work and leaves the Bitmap in the material with None for the file path.

Fortunately, as annoying as this is, Arnold will actually help you find the materials with missing maps. Open the Material/Map browser, either from the Material Editor dialog or the Rendering pull down menu, and then expand the Scene Materials rollout. Look down the list at the icons and anything that has a fully black sample slot surrounded by colored corner brackets has a missing map.

To correct this, copy these materials from the Material/Map Browser to the Material Editors as Instances. The sample slot for the material will show a black square with colored corners, again indicating that it is missing maps. Drill into the material to find the maps then check to make sure they have a bitmap assigned. If not, delete the bitmap from the material. As soon as all of the missing maps have been removed from a material, its sample slot will show in the Material Editor. Sweep through all of the materials and the file will now render properly.

The million dollar question is why does this happen? The answer has to do with procedural maps in Revit. Currently, they are not translated by Scene Converter and for some reason are switched to bitmaps with no path or file assigned to them. For some of the materials, like the Wall Paint, the map is assigned in the background through the selection of the Application parameter. In other materials, it will be applied to one of the map parameters. In general, you will have more control over your material if you assign a Generic material to the family rather than one of the Autodesk Pro materials and that allows you to better monitor and control these types of problems.

If you are using a centralized material library for Revit, it may be faster and easier to have someone go through and correct these materials in the Revit library rather than having to sweep for missing maps in 3ds Max each time you import a model. A new filter from Autodesk for the Scene Converter that would remove the procedural map automatically is another solution but it’s not here yet and we do have work to get done.

Happy rendering!

” (Note: the nature of IES file).

Method:

Open IES file with notepad, delete the special characters and then save it, open Max file to load new IES file, save it and then submit it.

Unable to read file information

Phenomenon:

  1. Failure to save Max scene information (Save File Properties) will result in the rendering failure.
  2. Related parameter information can’t be obtained during the analysis.

Methods:

  1. Customize in Max menu bar-- Preference settings—File-- Save File Properties.
  1. Enable Save File Properties to save the file and then submit it to the platform for rendering.

Modeling plug-in causing rendering errors

It’s recommended to convert some modelling plug-ins such as roofdesigner quadchamfer Railclone groundwiz volumebreaker scalpel rayfire floorgenerator to polygonal objects and then submit them to the farm.

Phenomenon:

Wrong rendering effects or Max crash during rendering.

Methods:

  1. Regarding roofdesigner, the below is the creation in Max scene.
  1. Select the model and right click it to find Convert To: Convert To Editable Mesh.

Rendering output TGA compression settings

Method:

The reason is that Compress is not ticked in outputting TGA, resulting in a large image output. Open the file to tick Compress.

External reference problems and the solutions

Method:

  1. Please check if the scene file is loaded with the correct external reference which needs to be saved in the absolute path of E~Z.
  1. Click Merge button, merge external reference objects to the scene, save the file and submit it for rendering.

Scene element path problems

1. Open max file and press “Shift + T” key to find the missing bitmap.
  1. Select the missing bitmap, right click > Set Path…
  1. Get the bitmap path in the pop-up window, click OK.

4. Save and resubmit it.

Gamma error

Phenomenon:

After you modify related parameters of gamma in the following ways, the brightness of the rendering result will be processed and saved in some files that support this effect; if you save the image with the unsupported file format, you may not get the brightness that you want.

Correct effects

Incorrect effects

Method:

formats commonly used and their ability to save gamma correction, select Yes opposite to the file type.

FumeFX cache file missing

__Phenomenon: __

Fume Fx cache missing when exporting rendering output.

Methods:

Modify the cache path to the E-Z disk letter path. Ensure a complete cache file is saved under the corresponding directory of the cloud disks E-Z. Submit it after confirmation.

Converting FP and RC to mesh objects

I. Ways of converting FP objects to mesh objects:

  1. Select the Forestpack object to be converted.
  2. Click “Utilities” icon.
  3. Select “Forest tools” and click “OK” button.
  1. Click “YES” in the popup box, and the forest object will be converted to mesh objects, meanwhile, max will automatically delete the forest objects created previously.
  1. The perspective after conversion is as follows, save the file and submit it for rendering.

II. Ways of converting Railclone objects to mesh objects

  1. Select the Railclone object to be converted.
  2. Click “Utilities” on the tool panel.
  3. Select “Railclone tools” and click “OK” button.
  1. Click “YES” in the popup box, and the Railclone object will be converted to mesh objects, meanwhile, max will automatically delete the Railclone objects created previously.
  1. Save the max file and submit it for rendering.
