The Scene is still very complex.
I get very low to unworkable framerates (FPS) with all models displayed and at 4 Star Editor
and 100 percent resolution.
Reducing the Editor Star
to 2 and resolution to 50 percent helps to improve FPS up to around 11FPS.
However, that is on a GTX 1080 which has much better performance than your Quadro M4000 (in the order 10000 to 6000 Passmark
On a GTX 980 it's even slower.
The problem is, that if you have reduced the quality of the imported models to their minimum, as per the suggestions in our articles Morten mentioned, then any further reduction to save some more 3D Points
may adversely affect the quality of those models, especially the 3d people.1.
However, just to confirm with you, that the models have been reduced?2.
What 3D modeling software are you using? Is it AutoCAD?3.
Are the 3ds (children) models being sourced elsewhere, that is, is there any option to reduce the model complexity of those?
The problems are two-fold when all models are shown:
1. 3D Point Count
is in the extremely high. We would categorize anything over 100M 3D Point as above the extremely complex, and that means the models are well above the guidelines of use for your PC.
2. The 3D Point Count
of the models is using a very large amount of the available graphics card memory and requires over 4GB of file size. It is likely that some data is being transferred to other memory which will be slower than the graphics memory.
I would suggest:
1. Save the three 3D Grass Materials
to file. Then when everything is ready before the render load those materials back in. It only saves 0.5M 3D Points but it all helps. Noted you have tried that.
2. To get some speed from Build Mode
you will need to work in lower resolutions. At 50 percent resolution and 1 or 2 Star it works at a reasonable speed here.
3. Import the children that are part of the current models separately so you can hide them, as they are the costliest models.
4. If you look at the models '.Lib' in the Documents\Lumion 9.3\Library folder you will see that the Q10381.lib file requires 1.7GB of file space, and in Lumion needs 3GB of memory and is about 36M 3D Points
. It seems that it is perhaps still too complex for the nature of the model. Can you optimize it at all by reducing its polygon count? There are of course tube based parts that still need to be kept rounded and not faceted.
But there are also lots of flat surfaces. Perhaps that model can be optimized some more and split in to two models for import so that the rounded parts can be hidden in a Layer
whilst working on the Scene
Repeat for model '137601 (1)' and then '231005'.
5. If you cant reduce polygons in AutoCAD?, you can try to do so with an external polygon reduction tool such as Polygon Cruncher
I see you have mentioned flattening the terrain. If a hills terrain is needed such as that in the Start
template Mountain Range
and in your Scene
you sent us, then that will require about 12M 3D Points
And lastly for one more question, how many more 3D people and other objects are needed? Can most of those be sourced from the Lumion 3D People Library
or will you be needing to import more from 3ds sources?
