Forest Pro (*) / Re: Very slow 3dsmax when making any new object with lots of forests in the scene

« Last post by K Gazzard on Today at 12:03:28 pm »

Thanks for the files.

It looks like this issue is related to the 'From Layers' feature being enabled in the object 'ForestSet_spline_CAD_natural_wood'.
This feature is triggering an update of the Forest objects each time a new node is created in the scene, or nodes are manipulated in the layers.

We'll try to improve this. Until then, we recommend to add the objects manually to the ForestSet, instead the layer option.

Additionally, Display->Point-cloud->Global density is set to 600%, which is hitting the viewport performance.
We recommend to lower this value, or alternatively setting the viewport mode for Forest objects to Proxy, which provides the better performance.

Thanks for your response. For now, with heavy spline references, I will manually add the objects to FP sets instead of layers. I wasn't aware previously that there was a performance difference. By the way, the point cloud set to 600% was just for the purposes of a previz playblast, I had forgotten to dial it back down before sending you the file. I normally work with these settings much lower or as proxy.

Many thanks for investigating this issue.

I agree that it would be good to have a slightly more sophisticated "update system" when using multiple FPs. For example, if I draw in one FP that references three other FPs, the whole drawing is slow. Wouldn't it be possible to make the FP so that only the selected FP is updated when drawing, and the others only when the mouse is released (stop painting)? This would speed things up considerably while almost keeping the drawing responsiveness.

Unfortunately we are limited by the 3DS Max notification system, which manages the updating process automatically.

Forest Pro (*) / Re: Slow Install

I’m sorry to hear that the download is so slow on your end. Have you tried using a VPN, as suggested earlier, to see if it makes any difference?

Best regards,

Render problem is solved, there was a problem with the scene.

I am having to reinstall my Windows OS, and again, 1/2 day day to download Railclone/Forest libraries. Something can't be right with this. I have fast internet, so unless I am downloading 100s of gibibytes of data, you need to work on this.

Thank you. When rendering I am facing another issue. I have strange render results, geometry is ok. Did anyone else had this issue?

Thanks,

Hi,

I’m sorry to hear you’re experiencing these issues. Since Forest Pack 9.3.1, a problem where ForestSet triggered a Forest rebuild when modifying layers — even if ForestSet wasn’t using layers — has been fixed. Based on your description alone, it’s difficult to determine what might be causing the issue. Therefore, if possible, please send us your scene so we can review it here. Thanks in advance for any additional details you can share that might help us identify the source of the problem.

Best regards,

OK, thank you - I have sent the file as requested.

RailClone Pro (*) / Re: SPLINE-OPS: Is it possible to "connect" multiple generated splines...

« Last post by Michal Karmazín on October 24, 2025, 03:11:12 pm »

You're welcome. That’s a really nice idea — filtering the spline sections by Material IDs is a smart way to keep things simple.

Best regards,

Hi Michal,

using CrossSection is a great idea as an workaround. I changed your setup a little bit with the Spline-Offset Modifier in combination with ID-Filters to get it right.
Thank you for the Idea. 

I attached the file, if you or someone else wanna take a look.

Would be nice if you could build in a cross-section function into the spline operators in the future. If you guys think it would come in handy.

Thank you and keep up the great work,
Denis
