I've linked various house types and some that repeat from Revit to Lumion.
Issues occur -
1) The house types that repeat all have slate roofing. When slate is applied to upgrade the slate material, each angle of the slate is different and looks odd. Just does not work, is there a correction or better method?
2) There is a lack of material options in general towards residential housing. Especially brick & slate.
I expected a lot more especially it being a pro version. How are various materials built up or easily modified?

Thanks,..

Hi J.

1. Are the other buildings mirrored buildings, or copied/pasted/duplicated buildings?

Please follow these instructions to make the roof material look correct on all surfaces:

Knowledge Base: How do you get roof tile directions aligned to the slope of the roof?

2. The basis is that if you are needing to assign a material in Revit, then it is the one to also use in Lumion.  That, however, is flexible and you can assign Lumion Library Materials to a surface or use your own.

When you apply one to the model in Revit it will be imported with the texture and color setting from Revit.  From there you can change its type from Imported Material to one of the Library materials or as a Standard Material.  For either, you can change any of the settings that can alter its look for rendering.  Including loading your own different texture to the Color Map etc.  The Map Scale value at 0 means that the surface will have the texture mapping as you set in Revit.  If you want your own (box based) texture mapping, then set the Map Scale above 0 to be the desired Scale, and from there you can change orientation and position.  There's more about that in the article below.

There are a range of material settings that you can use to change the look of any of the Lumion Library Materials.  Those materials are based on the Standard Material, so it might be worthwhile (if not aware of or done so) in seeing our article:

Knowledge Base: What do the properties of the Standard Material mean in Lumion 10 and newer versions?

There are also a range of options for more experienced users such as changing the depth of a material by changing its Normal Map, adding your own reflectivity or emissive masks etc. 

Please have a look at our Knowledge Base articles in the Materials Section.  For example:

Knowledge Base: How do Normal Maps work in Lumion?

If you find that there are other material settings or also other materials/textures that could be included in the Lumion Library, then please feel free to add your suggestion at any time to the Feedback and Ideas Board.  If you can also include reference images, then that helps greatly.

Let us know if you have more questions on either of the above.

Few urgent questions,

1) Roof slate issue on mutlipe roofs of the same house type. (Revit link)
Doesn't seem to be a good solution.

2) How does The photo match effect help me?

3) Material selections seem so limited.

4) Can i have more than 10 render images in any given project?

5) Trees set up in revit disappear when the project is linked. What's the quickest way to correct this.

6) Open street map is terrible. Can't move or edit once set. And only works if you have no levels. Which doesn't help.

7) Once scene is loaded and works been done on a project. Can i reload a different scene to current project? Or am i stuck with the default scene of your choosing at the start?

....

2) How does The photo match effect help me?

If you want real context placement of your design build.  A lot of users, when required to provide compliance information about a project to local or government agencies, are requested to show the project in the real-life setting, so with Photo Match, you can do that.  There are also two other techniques for making in-context backgrounds when you need to do a 3D animation or other 3D Photos, but those only need techniques for adding backgrounds to your Lumion Project file, so are covered in other Support Topics in our commercial section.

3) Material selections seem so limited.

See my initial answer in my reply earlier on.

Otherwise, can you explain some more what you are expecting for residential and some examples so we can relate those to what you can do in Lumion.

4) Can i have more than 10 render images in any given project?

Yes.  You can have 100 in Photo Mode - 10 Photo Sets with 10 Photos per Photo Set.
When you click on the next unused Photo Set you enable it and can then add Photos to it.  See attached picture 1.

5) Trees set up in revit disappear when the project is linked. What's the quickest way to correct this.

If the trees are RPC objects, then it is not possible to export those.  RPC licensing prevents export to other software.

To workaround that, you can create a simple shape such as a box for each of the trees and use the Node Replacement workflow.  This workflow allows you to export the Nodes, and then replace those in Lumion with objects from the Plant Library or other.

6) Open street map is terrible. Can't move or edit once set. And only works if you have no levels. Which doesn't help.

You mean the OpenStreetMap or your Imported Model?

If the former, then that is now by design to accommodate the real-world Heightmap system, where the OpenStreetMap is now fully real-world orientated  In other words, if the model in the 3D modeling software is correctly world aligned then all that should be needed is to place it in the Project.

The OpenStreetMap model can be moved horizontally by moving the marker on the OpenStreetMap map before downloading the model data again.

You can always move your Imported Model in Lumion by selecting the model (whether imported using LiveSync (direct) or LiveSync Export) and using the Move Tool or Rotate Tool, or entering values for the positions.  Are you not able to do that?  Is the Object Icon for the Imported Model colored red?  If so then it is simply Locked and you need to unlock it (see the Objects Options panel).

There have been a few comments and questions on the use of the new system, those answers are included in topics I can provide a link for you if needed.

7) Once scene is loaded and works been done on a project. Can i reload a different scene to current project? Or am i stuck with the default scene of your choosing at the start?

The New Project Templates (Plain, Forest Environment etc) are only available as a New Project.

To change the overall look of a Project you can use the Templates that you choose in Build Mode to select a look for the Project (Scene).  See attached picture 2.

Note that for Pro users there is also the Merge feature that allows you to merge in objects from one Project to another.

Thanks for your reply & answers.

Following on from my previous question 1:-
A particular house type design is linked to a Revit layout and copied/rotated as required to give various options throughout the layout. The issues with this, when slate is applied - it doesn't work. I've tried reducing the scale back to zero within Lumion and it reflects whats in revit - but at half the texture size. Its just a very awkward work around.
Is there a better solution?

Following on from my previous question 3 :-

To create a new texture, (brick &slate) - how is this done? As poliigon isn't free to use their textures. As a practice, we need various brick & slate textures for residential builds.

Kind regards,

J.

As the article Peter mentioned says, you need to follow these instructions to make the roof material look correct on all surfaces:

Knowledge Base: How do you get roof tile directions aligned to the slope of the roof?

So, once you've set the Map Scale slider value to 0, it will use the Revit texture placement. As you noticed, the Lumion texture might be too big or too small on your model (even though the orientation is now correct as it's based on the Revit orientation), and you then have to change the scale of the texture/material in Revit before re-importing the model in order to solve that problem.

As you pointed out, this isn't particularly streamlined but this is the only way to preserve the texture orientation from Revit whilst using a Lumion material.

You mean how to create a new brick or slate texture for use in the Color Map slot?

Or do you mean how to create a Lumion material once you've sourced a texture for use in the Color Map slot?

Thanks for clarifying that.

Can you please post some links to the products in the Feedback & Ideas section, so we can add them to the list?

The more specific the products are, the better.
