Title: Trees LOD distance
Post by: Aaron on December 09, 2010, 02:16:26 pm
It seems to me like the trees are jumping out of lod-0 rather quickly?

Resource issue or just configed that way?

For realtime preview this is the standard speedtree configuration. For movies they should be infinite range.

Should be Wink

Lumion_demo_Tree_lods

This is a resized full-HD render (photo-mode).

The quality of almost all trees is already worse then what they look like upclose.

The problem gets particularly annoying when rendering on print or poster format.

As these resolutions allow for many more details, one would expect the (speed)trees to up their details rather then stay the same or compress down.

My findings untill now only proof the contrary. The higher the resolution, the more obvious it becomes the detail on the trees is just too poor.

Please do note this is not about trees close to the camera or relatively close. All is fine in that aspect.

Would it be possible to adjust the speedtree config inside Lumion?

It is indeed true that in a large photo this gets worse. I'll add an option for calculating insane more detail.

I love the sound of that. Insane detailmode on/off.

Do I see a speedgrass button over the horizon here?

I know..pushing my luck Laugh

We have access to the speedtree grass of course. But it is so dense that the painting of the current grass objects seemed more flexible.

Would be great if this will get an update. It's really noticable when making an animation toward trees. Frown

We had many test versions of things like speed grass. The problem was that the grass was everywhere so it was not as configurable as the current grass.

Hmm ok, so it worked at least, no huge resourcehogs etc? Wouldnt it be possible to settle for the best of both worlds? Meaning the current grass as well as the speedgrass but the latter to be applied via specific material so as to not have it show up everywhere?

For big scenes it sounds like speedgrass would be very helpfull to get a sense of reality across (and very quickly at that), that cant be bad right :-)

Maybe... we can add speedgrass as an object like water so it's an optional effect.

If thats possible it would be brilliant for sure!

Yes, please! Laugh

from the update 1 beta log: - The LOD of trees for final movie and photo is now 10 times further

 

You guys sure?

Looks to me the trees jump out of Lod-O pretty much the same as in 1.0 Confused

 

Pics are rendered on Poster format, photomode.

I'll try it out but I am pretty sure. Maybe we are seeing a different effect in poster format.

Yeah please do. I think you'll find the problem varying from tree to tree but on most its pretty obvious they still do jump out of lod-0 very quickly.

 

I'd also like to propose a split between higher and lower poly trees.

Looking at the speedtree cataloque its just painfully clear that some of the trees are very poor quality and somehow it just doesnt feel right

to have those included between the good ones. The Alaska Cedar probably is such an example (very low poly) but there are more.

 

How does that work for you/quest-3d btw, are you allowed to just download these when you have a speedtree license or are there additional costs involved?

I'm hoping for the 1st ofc and if so, are suggestions for additional trees from the catalogue welcome?

Remember that the library you see might be of the old 4.x trees. Most of the 5.x trees look good I think. I think we included ALL trees of the standart 5.1 library but we can create our own with the editor.
Title: Trees LOD distance
Post by: Aaron on December 19, 2010, 04:01:28 pm
Yeah the 5.x trees are quite a leap forward from the 4.x ones for sure.

I'll try to compile a list of the good vs the not so good ones once I have some spare time...

perhaps it'll come in handy for some, perhaps its useless, dunno :-)

When speedtree.com is back up I'll also see if there are some additional trees. I think I do recall seeying a Poplar for instance.

I've done some per tree tests and the look and feel of most ranges from very acceptable to quite good.

If taken into account these are all speedtrees then their value increases even more ofc.

 

There are a few that perhaps deserve a closer look:

 

-Weeping Willow

-Alaska Cedar

-Sample Conifer

-Loblollypine (copy of sample conifer?)

-The chinese Pines (Welcoming, Huangshan etc)

 

Probably all of the above are let down mainly by their poor quality billboard textures. Either the resolution is low, the billboards are too obvious

or a combination of these 2.

 

Regarding the speedtree catalogue:

It seems to me there's still a considerable amount of assets available that could be considered for including in Lumion.

Even with the 4.2 tree packs, many of these still look pretty good (at least in the catalogue viewer?)

With the 5.x trees there is the amount of polys that's probably been a major issue in considering whether to include them or not.

I wonder if it's possible to include at least some of the full versions (ranging anywhere from 100 to 400k+)? Albeit perhaps via a high-poly installment seperatly from the main installer if download size would increase exponentially otherwise.

 Imo Lumion could use a seperate category for exceptionally good looking speedtrees. Seems fair to the rest of the product :-)

Just 1 of these in your scene can be of great value and well, ofc it should be a no brainer these would not be intended for larger amounts then just

a couple max.

I tried some of the non realtime trees in realtime but that was not a great success. Some look much better then the RT counterparts of course. The 4.2 need a special conversion that we didnt have time for yet. But we will keep updating the tree library of course so stay tunned what we are able to get out of it.
