First Animation Test

This is the firs animation test of a new VR project at Urizen.

It will be a representation of a large wood cutting machine for a  client that produces saws for those machines.
At the end, you will be able to see the entire machine and get some details about the saws and where they are inside the machine.

As the project progress, I’ll post more things.

Cat 793D

Hey there!

Another model was done.. this time is a huge truck from Catterpilar called CAT793D.

Iray03  Maps

This model was done for being used inside unreal, so I’ve had to do some minors adjusts in design and remove some things that was not important.
I’m guess that the size is a little big than the real one, but it’s easy to adjust inside Unreal.

You can see it em VR if you have a Google Cardbord at Sketchfab.

Vehicle

This week I’m made this vehicle for the simulator.
No more words… Here is some screenshot  in Substance Painter and inside Unreal 4.

The final result is still different between SP and UE4… I’m not shure why.  Maybe the lights, or reflections. I don’t know…

VR Locomotion Test

Two nights ago, I’ve started to develop some locomotion test for the simulator that we are developing at Urizen.

This idea takes one button to be pressed that enter in “locomotion mode”, with the head you point at the location and then you are smoothly  teleported there.
This not  only reduce simulation sickness but also removes the movement of the joystick, because our player target almost never is a gamer.

When you look at a place, the system will take in account the width and the height of the player to allow the movement.

I’m will expand this with a ribbon that show the trajectory from the player to the point to make it better to see.

Still running good in Unreal, but I’m don’t have tested at Oculus yet. Maybe I do not need to make any optimizations. 🙂

Here’s a video showing the actual stage of the system.

Electric Panel

After a few hours another model is done. This time is an electric panel for the simulator.

Here’s the side-by-side with SP and UE4.

Security Tape in Blueprints

Another procedural object for the simulator, made this time with Cables Components: procedural security tape.

SecurityTape

Until now it’s only a cable component that goes from start to end point with some adjusts, but if I had time I’m will expand or trying to made with splines.

Here’s the Blueprint.

Spline Chains with Blueprints

Little update at my “chain system” with splines in UnrealEngine.

Chains

Basically now I’m can chose between colored or chrome chains, and also chose their 2 colors and the numbers of knots that are colored.

For those who like to learn, here’s how it works.

ChainBP01

The chain is an Actor based Blueprint, with all code in the Construction Script.

Image_01

The spline actor spawn instances of chain knots based on a division of the spline length and some variable that will be the space between the instances.
Using Instanced Meshes prevents additional draw calls since the mesh is instanced.

After that, it rotate and position the mesh based on  the distance that object is along the spline.

ChainBP02

Next, with the modulo (%), we determine if the object must be rotated 90° or not based on “Even and odd”. One is rotated, another is not.

ChainBP03

The branch defines if the chain has color or is chromed. Here the things got a little confused… and this was the only way I could make it work.
If it has color, the chain need to paint every color based on the number defined in the variable Stripe Units. So, with a greater than (>), we change the material’s vector parameter of the first block until it reaches the number defined in  Stripe Units.

ChainBP04
After that, with the “Do N”, we change the other block of knots with the another color. After that, it performes a reset of the “Do N” and reset the temporary “Stripe N” variable.

Probably there is another (and better) solution for this part of the BP, but as long its working, I’m good with that.

With the actor blueprint in scene, you just need do right click anywhere over the spline do add a spline point and change the tangents to make the chain look as you need.

Thanks a lot.

Another week has passed…

Hey there! Another week has passed and I’m still not touch the game and that’s because I’m have so much fun working with Substance Painter and UE4. \o/
After make some modelling, I’ve used SP to paint the materials. The program is so much easy and fun to use that bring fun to the job.
SP   Image_03

That being made, it’s time to import and see what’s happening within Unreal 4. I’ had to admit that the material inside UE4 is a little different that in SP, but the result is still greatly amazing.
With a few little adjusts, the material behaves as desired. Of course there’s almost no work with the environment lights and Post Process, but I’m sure that will be good in Oculus Rift.
Lightmass is slightly modified in the .ini file, but all other configs are default.

This is inside Unreal 4 with a few cables at the top of the poles.

I’ve also had made a spline that duplicate a instance mesh of a chain in order to make the chains more flexible and easy to adjust inside Unreal. Unfortunately there is no physics build in splines, maybe another time I’ll make something to simulate that.

See ya!

 

VR and UE4 for Simulations

Hello!

While the game is in hold, I’ve decided to continue with the Dev Blog by showing what we are testing or developing  at work in Urizen Technology.

We are developing a simulator in Unreal Engine 4 with the Oculus  Rift, and here is some screenshots of a container of electrical transformers.

SS01  SS02

The environment are placeholders, there’s no work with lights and Post Process at all. And as you can see, the doors are missing and/or is a single plane. I’ll update with more screenshots soon.

Here is the original.

See you…
