Thank you for your interest in Lumion.
If you have downloaded a version from the Lumion web site, then please be aware that is an older version 5.3. We also have a newer Trial version at 6.3 that you can use to evaluate Lumion. Refer our Knowledge Base Article
: Trial or Demo Versions of Lumion
Now, on to your questions: 1. accurate dimension within Lumion to a wood flooring texture:
No, that is not currently possible. There are some options to make that work: 1a.
Real-world dimensions for textures, for example wooden boards that show the groove or cut for multiple boards, are best designed and created within an image editor or texture design tool. From that you would then apply it in your 3D modelling application, then import to Lumion. 1b.
Some modellers will create the surfaces as individual boards with required dimensions, and that makes it easy to apply a generic wooden texture, both in the 3D modelling application, and as it imports to Lumion.
In this case any model already in Lumion can be easily updated using Reload
, after the model is changed from a 4inch to 6inch board. You can also export and import selected parts of a model, and show both options when needed. 1c.
As the model is in real world dimensions, it could be possible to simply use a measuring tool (you would need to make one) where you could place the tool next to the surface and then use the Scale
slider to get an 'as close to' for the texture.
Note that all textures are Tiled
textures, so non square textures are best applied in the 3D modeling application so that Lumion can read the correct UV settings for the material.
We have similar issue sometimes for ceiling tiles.2. emissive materials:
material is only emissive, that is it glows, but does not cast light and shadow.
Users will sometimes set the lamp or lamp holder part of the model to an Emissive
value without adding Spotlights
. This then gives appearance of lights in the room. Then use some well placed Spotlights
to create some shadows.
An alternative (sometimes) is to use a texture with white parts and use the Emissive
mask to brighten only those parts. Refer our Knowledge Base Article
: How do you make some parts of a material more emissive?
If you find the room is for some reason too dark, then you can also control aspects of the Shadows using a Shadow Effect
. You can also add some OmniLights
or Fill Lights
to brighten it. For those, be aware that OmniLights
are general fill lights that render extremely fast. The downside is that the light from Omni Lights
pass through all objects. It's also possible to add some additional Spotlights
and use those as broad based lighting by increasing the Cone Angle
up to or near maximum, so that they add soft-edge lighting and cast some shadows.
The Global Illumination Effect
(Pro version) are also used to add additional light (bounce) to both interiors and exteriors.
You can also make use of the Nodes
Feature for placing lots of lights, refer: Lumion 5.0 released
. Where there are lots of lights then make sure they are set to Speed
Hope this helps answer your questions.
