Let make myself clear. Suppose I want to have a road. If I apply the asphalt material from Lumion, its a nice and all, but its gets pretty repetitive across the vast surface of the road.
Wouldnt it be possible for me to map a large bitmap of a road, with potholes, skidmarks, asphalt paintings (pedestrian cross, etc), utility holes, etc... and then MIX it with the default Lumion material, which is more detailed UP CLOSE? So as to have variety for the large scene and get up close and see the nice details of the default material?
If not, what if I just want to apply a detailed asphalt bumpmap over the large road texture? Because it seems to me that in Lumion the size of the bumpmap is always equal to the size of the diffuse texture... you change one, you change the other.
If I have an asphalt texture for a large area, lets say, 20x40 meters... and my bumpmap texture is for a small area 1x1 meters... I suppose the bumpmap would be stretched by Lumion to cover 20x40 meters? So the fine grain of the asphalt bumpmap would actually become big boulders bumpmapped?
