Garrett house

Lately, I've had some lightbuild issues that crash the engine, and these types of errors are quite time consuming. So, while I have been troubleshooting this problem, I modeled the Garrett house, a farmhouse which once stood nearby the high school at 201 East Washington. The home was demolished in 2002 to make way for green space around the high school and middle school.

Grotesques and other details

Only a few more architectural details remain before I am ready to render v9.5 of the flythrough. The big items are the grotesques from the front facade (as seen below). I don't have enough source images of these carved limestone figures, so photogrametry is not possible at this time. Instead, I used the same technique I utilized on the main entrance foliage, and mapped a single photo over a manually modeled mesh. A height map created with Materialize adds a touch of tessellation. This method creates acceptable -- albeit temporary -- results.

In addition, I completed the brick box ornaments on the rear elevations...

...and finished the wood/brick wainscot going up to the visitor's box in the gym. 

These stairs were still unfinished in the previous flythrough video

The difficulty was that the angle of the wood wainscot is 41º (not 45º, which would be easier)

Main entrance foliage

A small amount of stonework from the front facade of the building is still missing -- as in, I have yet to include it in the rendering. To expedite this, I am trying a new technique of 3D modeling. Some of the stone foliage is beyond my skills to model manually, so I am using Materialize from Bounding Box Software to generate texture files from photographs. I then create simple 2D outlines of items, then use the height maps created from Materialize to simulate depth (technically called "parallax displacement"). The results so far have been promising.

The same photo after processing with Materialize.
It doesn't look as impressive as a screenshot, but believe me --
those leaves look like they are popping out of the stonework now. 

Rough outlines of the leaves are traced in Blender, and UV mapped to match the original photo.
The extra vertices in the middle of the leaf are added because it makes the tessellation work better in UE4
(more opportunities for displacement, maybe?). 

Foliage added to the entrance arch in UE4. 

The software is open-source, and free to download. A YouTuber explains how to use it (https://youtu.be/vtnJToPxBNo), but it is mostly self-explanatory. 

Summer 2019 progress

Between now and my previous post in March, 2019, I have indeed worked on the UHS:1914 project, but not entirely in a way that can readily be presented in the blog. A majority of the work has been to write original music for the v9 video, and although the music is completed, the demo recording is not ready to be shared. There have been numerous items to correct/fix/add to the project, but since the music is complete, the timings for the camera cannot be changed. This means anything I add in the meantime will be fixes or additions that can be seen in the v9 video. These are some of the items added this summer:

Side and rear gable ornaments for the tower, including editing the stonework to look correct from the rear (it can be briefly viewed from the art room skylight in the video). I created a new version of the brick texture (originally from Polypixel) to make arranging fancy brickwork faster:

I finally found a solution to the square around the doorway arches. Previously, I used a square mesh that had one edge matching the arch, but this resulted in rendering errors. Now, the wall is seamless:

Cast iron balustrade remodeled to be more accurate:

Based on a photo from within a storage closet built in the former light well, I modeled the brick ornament on the exterior wall between the windows:

Gym balcony rail added around the entire perimeter:

A redo of the brick texture on the gym stairs no longer results in bizarre streaks:

Bookshelves are added to the Board Room (not completely accurate, but these did not require the creation of a new bookshelf model):

Because of the automatic LOD (level-of-detail) creation, the proscenium always looked "spiky" from a distance. I corrected this by optimizing the original mesh, which turned out to include the unseen (but still rendered) backside of the arch. With over 1000 fewer vertices, there are no more spikes! Also seen in the following before/after screenshots -- the crest used to be "floating" from the proscenium, and now is attached.

Before, spikes from the LOD 01 and 02

After optimization, no spikes!

A bug cropped up in the UE4 project files causing the editor to crash unexpectedly when copying actors. My intention was to update the gym portion of the project by adding exterior details from the 1914 side of the building (trees, houses, corn, etc), but this kept making the editor crash. A time consuming solution fixed this, but it involved splitting the building into multiple sections. This meant copying every actor (UE4's name for separate items) to new levels that are ultimately viewed all at once, but can create cool/unsettling views mid-way. For example, below is a screenshot of the building with the exterior walls peeled away:

...and here with the auditorium in various states of hidden-ness:

When the music demo is ready, I will post it, along with the updated video.
