Making its debut in 1998, the first generation Unreal Engine integrated rendering, collision detection, AI, visibility, networking and file system management into one complete engine.

With the level of integration used, some trade-offs were necessary to maintain performance levels with the hardware that was available at the time.

For example, Epic decided to use cylindrical collision detection over the IK collision detection system in an effort to maintain playable framerates on systems that were common at the time of its release. Internally, Epic used this engine for Unreal and Unreal Tournament.

When the classic shooter Unreal came out in 1998 it was praised for its rich graphics and innovative gameplay. Rediscovering these great old-school gems is tons of fun, and what better way to do it than with some crisp and beautiful graphic updates. This HD texture pack along with the HD Skins mod makes Unreal truly shine!

There have been HD textures available for Unreal for a long time now, but it was a work in progress. DiehardSCSW started the project, and did a whole lot of great work which is included in the pack. In January of 2019 I decided to take on the job of fully completing the Unreal Retexturing Project (URP). I had done some HD textures for the URP way back in the past. In terms of the scale of the texture pack - It's pretty big. There are well over 2000 textures in the project and more that half still needed to be remade in HD or fixed up.

There is a version of this pack that is server compatible with Unreal (227) and also Unreal Tournament (UT99). The texture pack is mainly intended for Unreal single player, but many single player mods run on the UT99 platform, so it exists for both. This release does not intend to cover all of UT99s textures- just the ones in common with Unreal. Maybe I'll take on the UT specific textures in a future pack...

Unreal HD Texture Pack 2.0 for UT99

Throughout the process of making this release, I have been collaborating with Lightning Hunter, who has done the HD Skins mod. He is also releasing a 2.0 version of that mod, so please check that out and use it with this pack!

I think they should release this engine for free...

Reply Good karma Bad karma+5 votes

yarp. but epic fears the UE1 modders... they really do

Reply Good karma Bad karma+8 votes

Unfortunately even to this day the engine isn't free at all. I wonder why considering how UE3 can be used freely for free projects.

Your a retarded if you wanna know

this really need to be rewritten first it says this :

32-bit colored 512x512 size texture support

then further down it says:

High resolution texture 1024x1024 size support

i know for a fact that the first release of this engine only supported up to 512x512 textures and only later in 1.5 they included the 1024x1024 support
(never released only for tech demos)

Reply Good karma Bad karma+2 votes

with an advanced renderer the unreal engine 1.x CAN draw textures up to 4096x4096 pixels (8-32 bit)

Reply Good karma Bad karma+2 votes

The thing is -- Unreal and UT99 used raw UNCOMPRESSED textures!
Imagine that!
The engine actually could support much higher res textures at that time :D

The mother of the Unreal engine tree, which is the most used one by video games. It does a good job in both Deus Ex and Unreal Tournament.
