* LightWaveRTG recoded by 70lk13n *
***********************************

After more than 30 years, an update to the Amiga's most iconic application is finally here! It's a huge update
for all amiga systems with RTG and Piccaso96 drivers (Classic Amiga with RTG graphic card, Vampire, Pistorm,
MorphOs, AmigaOs4, DraCo...).

It's based on lastest Newtek release Lighwave5.00r and Modeler5.00f.

-Reverse engineering and new code by 70lk13n.
-Additional help with Lightwave things by Kikems/AmigaWave.
-New icons designed by SantiDarkG and adapted by S0yS0y.
-LightwaveRTG CGI Promo directed by Oscar de Palma and provide additional contents exclusive for LightwaveRTG
in OP3Dlw folder.

A project made by Amiga fans, for Amiga fans, 100% free.

LightwaveRTG *** What's New***

-All NG Amiga compatibility issues are gone, no more tricks or workarounds to run Lightwave on NG or RTG systems!
-Native RTG screen support, with screenmode configuration app.
-Ready for lastest P96 drivers.
-Blazing-fast GUI and screen redraw routines.
-Say goodbye to stack overflow errors between Layout and Modeler.
-Brand-new internal RTG render output in full 24-bit color.
-Real-time surface preview render on RTG.
-Render preview/feedback now in stunning 24-bit color, live while you render.
-Anim preview now works in RTG too, background color included, in 24-bit.
-Save and load your Anim Previews.
-Image stamps in gorgeous 24-bit color.
-Background images and sequences in 24-bit color, for both Layout and Modeler.
-Datatypes support (got PPC datatypes? Use them!).
-Sleek updated interface with movable panels.
-Color wireframe selection mode (it's a bug since 30 years before now unlocked).
-Increase render speed up to 20%.
-Now you can open multiple instances of LightwaveRTG.
-Plus tons of small fixes and speed improvements under the hood!.

Updated for v1.1:

-Layout red pointer fix.
-Now render preview use same layout screen resolution.
No more screen switch between render preview->layout->RTG out.
-Fix advance and previous frame step button for player in anim preview.
-Fix anim preview controller panel fail when move over layout area.
-Fix speed anim preview options for OS4.
-Fix Modeler loading Truetype1 fonts.
-Added Muadib3D content and some tutorials (@amigamuadib3d in youtube)

****** IMPORTANT *******

1- If you use AmigaOS3.x check that you have lastest P96 drivers and last version of icon.library fom Aminet.
2- In AmigaOS4 if you use Locale prefs laguage with Euro support you lost native Lightwave font for interface, choose
any language without Euro support when use Lightwave or define a topaz font in screens peference icon.
Our friend Javirulo will share a fix to force Lightwave to use Topaz Font if you need use Euro locale.
3- We recomend use 32bits, 24bits or 16bits screen modes but if you have a slow RTG card or limited Amiga system you
can try with 8 bits screen but maybe not all features works right.
4- If you have previous version of Lightwave installed, sure you have ModePro or similar screen promoter with entries for
Lightwave and Modeler, remove this entries. Also check that you not have older lw-config or Mod-config files in
env-archive or s:

***** SUGGESTED ADD-ONS*****

-Midwan shaders and plugins for Lightwave5.
-Lightwave 30th anniversary edition if you want make a clean install for Lightwave from original Newtek VideoToaster CD.
-Muadid3d and Amiga Raytracing Society for more tutorials about Lightwave.
-WaveGuide for use as manual for Lightwave.
-WarpDT for faster datatypes.
-Icon.library from Aminet.
-Lastest paid P96 drivers.
-Hyperion AmigaOS 3.x.
-New 3Dconverter for convert thousand of objects formats to Lightwave5. Available for 68k, MOS and OS4.

@kikems

Congratulations !!!!very goooooood news 😊

@kikems

Truly amazing update thanks to all involved

@kikems

Wonderfull work! Looking forward to it.

AWESOME work!!!!

wooohuuuuu

Here a video small video showing at first time LightwaveRTG working on OS4.

Here another video where we talk in spanish but you can see how it works.

in few days the release.

Well done!

The final version is very close.

Yesterday, we managed to unlock a bug that had been lying dormant or inactive for 30 years.
The code was already present in the Amiga version but wasn't working. It involved color assignment for different objects in the wireframe—a feature we had only seen on Mac and PC and assumed was never implemented on the Amiga—yet the code was there all along.

Also we adding new content made by my friend Op3dlw.

@kikems

Amazing work, always cool to see something as old as this getting fixed.

pretty amazing stuff. how do you do it? decompile with ghidra or resource? compile newly modified version? then provide patch binary so you're not distributing the original?

@NinjaCyborg

More or less, yes. 7olk13n do the hard work, decompile with Ghidra, locate routines in asm, modify or add new code and recompile.

Wow. I always lamented that Commodore could not hold itself together long enough to see RTG more cemented and see NewTek stick with Amiga LW longer, for this sort of thing. I am very excited about this project.

I'm excited to see this in action!

You talk about AmigaOS4 and MorphOS support; is that API compatibility, or is there PPC code available?

Cheers,
Bill Borsari

AmiWest!

I'd update first post of this thread with download link.
In few days we build patch files for apply over original Newtek install cd and upload to OS4depot or similar Amiga places.

Enjoy Lightwave for Amiga like never before.

@kikems

Thank you to all involved in making this.
Working great on my X5000.

Woooohoooo!!!

So Happy to see another link posted to a website that hates Amigas!

Wonderful... *No* Amiga browser works on that URL.

:/

PJS

@pjs

You are right, I'll drop download link now, sorry.

@kikems

and a small fix/patch for AOS4 users:
Script to patch Layout.fp and Modeler.fp so font "shows" ok under AOS4 when using languages (Locale prefs) with charset different as ISO-8859-1

***********************************
NOTE: only valid for AmigaOS4 users

Needs:
gpatch from os4depot (https://www.os4depot.net/?function=sho ... ility/filetool/gpatch.lha)

See README please.

@tekmage

No PPC, lightwave continue as 68k app for now, but now use datatypes of your AmigaOS, if you use PPC AmigaOS you use PPC datatypes for load textures, image backgrounds with the speed of PPC code.

This means that now is a good idea update your OS datatypes for alternatives more faster like Ak or DTdatatypes or maybe some newer and faster datatypes from Aminet/Os4depot....

The main reason because I'd say now is ready for NG is because previous versions works partially on OS4 loosing features that need access to OCS and you need modepro and other tricks to try to use an unsable lightwave on MOS or OS4.

Now works on this NG systems without issues or crash, no need tricks, and no calls to OCS. More features than never and faster speed, but continue with 68k code.
