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.

Pneumatic Rig for Unreal

After some hours of working, I’m manage to resolve this rigging in 3Ds Max. It consist of a pneumatic arm, of a cutting tree machine.

With some links and “Look at Constrains”, here’s the result and the object Hierarchy.

As soon the animation is ready I’ll post a video of the object in Unreal 4.

Procedural Mesh Slice in Unreal 4

Last week I made a little test to see what can be done with this new slice feature that Unreal release in 4.13.

After a little headache working with obj and  Exccel to make array of vertices, I have found great solutions in Youtube.

First of all, the most great node that I found is that “Copy procedural Mesh from Static Mesh Component” that does what it says. It makes a procedural copy of a static mesh component, so you can use at will.. No need to make an array of vertices, and triangules to make you procedural mesh. Just put a static mesh component and it’s done.

After this, a little of Blueprint and you can make great results. This is a great feature (especially for VR), but unfortunately is a little limited. The cap is single-sided, and don’t accept holes in.
One great, and most important things is the ability to get the normals of the plane cut, making the cut really precise.

With little effort, you can do a generic “Fruit Ninja” eheheh

 

Cat 793D

Hey there!

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

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.

VR “Look At” Interaction

For the past few months, between some modelling and texturing, I am using Oculus at my work to create a VR simulator that open a whole new world of good stuffs 🙂
VR still is a new and “working in progress” technology, but the possibilities is huge!

So… I’m making some VR interactions for this simulator and going to share here some things.

Grabbing some things here and there, I’m working at a look at interaction… For now I’m having a relatively simple UI material that will drive a interaction based on time.
This will be apply in a 3D widget and a timer will drive the interaction, so the player just need to look a certain amount of time to the objects.
Have some help from Mitch’s VR Lab, witch has some really good VR stuff.

Here’s the material instance:

And the shader:

I’ll post the finish product as soon as possible 🙂

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.

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.

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…
