The Tree

Douglas Firs (Pseudotsuga Menziesii) are tall, slender conifers native to the American West and cultivated worldwide. These adaptable pioneer trees take root in a variety of biomes. They serve as the backbone of ecosystems and logging industries alike.

The diversity of Dougs allows them to resemble a variety of other tree species, resulting in several confusing names. Indeed, Douglas Firs aren't true firs, but rather a unique member of the pine family.


This is a pack of 22 unique assets including 15 living and 7 dead trees.

Holy cow these were a journey. I started these using the same modeling techniques as my Western Hemlocks and Redcedars, but I didn't feel like they lived up to my expectations; so I came up with a new modeling technique and started over from scratch. I put a lot of research into making these my most authentic trees.

I have more Douglas Fir packs planned for the future, including a pack of ancient Dougs that ascend to pre-colonial heights. This pack includes more typical examples.

Having done these, I feel like my Hemlocks and Redcedars no longer live up to my standards and I hope to redo those as well when I can.


Douglas Firs can be found along the Pacific Coast from Canada to Mexico, with smaller stands growing as far east as Colorado and Utah. Younger Dougs also appear in many other temperate climates where they've been cultivated.

These hardy trees often act as pioneers, rapidly growing to canopy height after major disruptions like large fires. Only later do other shade tolerant trees fill the canopy gaps. Therefor, Dougs are typically the tallest trees in a given stand.

Taking centuries to reach full maturity, the tallest Dougs should only appear in pre-colonial old growth forests.


- All 22 trees in the pack share two 1k x 2k texture sets. The Loading Screen Mod should eliminate the vast majority of functional RAM requirement for this pack.

- Tri counts are average for trees of these respective sizes. The younger trees are mostly under 1k tris which makes them fairly light for most users.

- I did NOT alter tree sway on these assets. Based on my experience with the previous packs, I now recommend using the Tree Movement Control mod to reduce sway, which can eliminate sway on LODs as well, and doubles for random tree rotation.

- Tree LOD Fix is critical as always, and the larger trees may warrant Ultimate Level of Detail and/or Adaptive Prop Visibility Distance.

Thank you for this mod. I happen to live in Whatcom Co. where the largest Dougie was cut. I'm gonna due a fictional loosely based Whatcom city and will need some Dougies.

Hello Greyflame!

Iam using this asset in the map I have just made.
Probably you wanna see it.

Thank you very much for making it.

Thanks everyone!!

@Perry7484 (Lo Rei dels Libres) - I'm still kind of learning how to do deciduous trees well, I find them more difficult, but Bigleaf Maple is very high on the priority list and Pacific Madrone just got added xD

@AWESOME CATS - Sitka Spruce is on the list too, might take me a bit to get to that one but hopefully not TOO long!

As someone trying to make believable Northwest California cities, this is god-tier awesome.

Any possibility of deciduous trees (bigleaf maple, pacific madrone) soon? :winter2019happydog:

Though i’m deep within Sitka Spruce territory (not quite the same), as a Northwesterner, this is awesome.

Now I can finally get started with my Pacific Northwest themed city, with all of the appropriate vegetation. Douglas-firs, western hemlocks, western red cedars, Sitka spruces... that will get really dense, really fast.
